When cleaning battery terminals use dilute white vinegar on leakage from alkaline batteries (then neutralize with baking soda solution) and a baking soda solution on lead acid battery leakage. unless you neutralize the residue it will continue to corrode. Pencil eraser will usually clean the contacts. The black oxidation on the copper wires in copper sulphate.

Today I bought this watch but the brand was Sutton. It's an exact copy. Luckily not only does the watch run, there is no corrosion on the battery terminal! Woohoo! Thanks to your video, I learned so much about this watch. I had no idea about the light. It's very very cool! This is the second watch I own that has a light. I also have a Seiko quartz from the 70s with light. They are both cool watches.

This is an absolutely gorgeous and cool watch great job fixing it

Hi. I have a reccomendation for removing items that are glued together. It's a technique that I,ve used to disassemble plastic model kits and it works really well. Immerse the part in warm soapy water water. Place it into a plastic bag and then put it into your freezer. Remove the next day. As the water freezes it expands and seperates the parts. ps I really enjoy your videos. Col.

Well worth the work! I’d wear that every day! 👏🏻👏🏻

I has a really good result on battery oxide with WD 40 put it on wait a few minits and it comes of easy and it dont harm anything.

Love jump hour watches. One day I'll get around to fixing my one.

Another Sicura watch that I absolutely love. Have several jump-hour watches and his would trump the lot. Bought my first Sicura (a Memostar) on the back of Nekkid Watchmaker's refurb. Got it from a guy in Liverpool, fully refurbished. Keeps excellent time, put a nice tan leather rally strap on it. That light is boss.

Great to see your out & About ,take it Steady

Your glee when turning on the light was excellent! It's really the little things that can bring great joy :)

Mike, I enjoy watching you tackle watch movements outside of your comfort zone. One Tenor Dorly jumping hour in my small collection. As stated above, they’re so creative and cool. Thanks for sharing, Mike!

Another suggestion from the world of model building. Use a glass fibre pen for cleaning off corosion around the battery contacts. It's very effective and you can work in hard to reach areas. Just be careful because you will get glass filaments stuck into your finger tips. This hurts. Col.

Great to have you back!

There's a Sorna version of this up on ebay. I had a surprise find from my Indian chap, a quite old Orient split day-date, very very pleased and to make amends for my last Orient not working he's chucked in a Seiko 6319 railway time square in black rather than me waiting six months there and back so I got that Orient surplus if you fancied a go :) It did surprise me it broke as unusually for an Indian it looks pristine inside, abs spotless with all the rhodium plating unblemished.

Thank you! That's a lot of fun.

Another great video, i agree with Sportclay1 for the use of white vinegar for the battery acid, then IPA

White vinegar safely dissolves battery corrosion on electronics. It is as easy as dabbing with a Q-tip soaked with white vinegar and wiping as corrosion is dissolved.

Hey Mike great Job. Crazy Watch😆

I really like your videos. Especially since you also show when something doesn't go as planned. Happens :)

Nice one Mike, happens to have exactly the same somewhere...

Hi how are things? A piece of advice: to dissolve the sulfation of the batteries, it is best to use cotton swabs dipped in a carbonated drink such as a tonic. It dissolves it without attacking the surfaces. It is applied and rubbed gently and then dries, and it is perfect.

Buck Rogers's watch!! Directly from the 25th century.

I was expecting a really weak glow from the watch, but WOW it lights up like Blackpool pleasure beach! I could sense the frustration when you were pinging away at the spring and was saying come at it from the other side...then ping! 5h1t happens dude, I fumbled holding a movement and it flipped out of my hand, I managed to catch it before it hit the floor but the fine seconds hand had bent into a near perfect spiral as it span out my hand, I then spent 2 hours straightening it with 2 sets of plastic tweezers with flat faces. Love the collection.😁

Fascinating watch. Love it, as you say they're all a bit bonkers, perhaps that's why we love them so much. I've just obtained my first jump hour watch to work on. It's an Adrem I believe the were sold by H.Samuel the jewellers. Thanks for sharing.

That is a cool watch...

Nice, My favorite Jump Hour Watch is a Hoga Directime or also sometimes branded a lip .

Hi, and thanks for this video. I‘ve collected some of these jump hours as well, and there are some special items, you should be very careful with: For instance jump hour watches with Otero 796 movement (f.i. Pallas or Stowa) may never be turned anti-clockwise because the spring which moves the jumping hour disc breaks very easily if you do so. Furthermore be very careful with all Förster Fb 221 - 225 (the last watch you showed us in the vid with date-disc may have such a movement, there even exists a Fb movement with day and date disc), as the friction of the minute wheel is achieved by a special coating on it, and if you clean it in an ultrasonic or Elma cleaning machine, you will have nearly no chance, to see the minute disc moving again, although the movement itself works. There is simply no more friction left. Stay healthy my friend !

I just love your videos, because they are full of passion and perseverance. To bring this "Mickey Mouse" watch back to life is a feat on itself. Just stop apologizing all the way as you are doing a great job and come across as a very nice guy.

Thanks, Mike! Love your videos...

First, this watch is very interesting, I really liked its different design. Secondly, this song, Maple Leaf Rag, is beautiful. I've never heard this song before, and I've never heard about Scott Joplin. Thanks for sharing some good content and good music. I like to share a Brazilian musician who composed songs in these lines. Search for Tico Tico no Fubá by Zequinha de Abreu. It's an amazing song.

HI! wath a coincidence, I have One, but don't fuction, I need do the same work tath you did. Great watch. Congratulations. Be carefull. Regards since Mexico City,

Well worth all the agro just to see the light. BRILLIANT!

I cheered with you when the light worked! What a great watch and a worthy addition to your collection. Good job!

Необычные, интересные часы!

that's pretty cool !!!!!!!!

Really enjoyed this one, as you know I’m a bit of a jump hour fan boy😂

very interesting

Just wanted to get one from eBay for adequate price, but now I’m loosing hope since all clip watchers will start to hunt those instalights. Good video, pal!

im happy you are get back and i am in joy to see you repairing watch 🙂😊😉

Wow Mike what a collection you have. They are very fascinating watches. That light is bonkers. Certainly a style of watch for certain occasions or mood.

Brilliant vid mate 👍 I've always wondered about these jump hour watches ....and now I know .. I really hoped the light would work ...very cool

Great video 👍. I had a Jump hour when I was a kid, loved it.

Great video. But my OCD is bugged on the manufacturing mishap, the 3 circular cuts above the upper glass, the one on the far right is slightly lower by a millimeter then the far left circle. Not your fault. Just the design.

It's great to see the failures in addition to the successes ;) its a realistic cross section of the hobby

My understanding is that the 17 jewel limit is imposed by import duties in some markets. So, if you have a pin pallet movement that works well enough - as this one does - you can spend those two extra jewels on additional pivots.

I’d wear that!

I was wondering how the movement was electric, but it appears that the batteries are purely for the light. It’s definitely worth cleaning all that corrosion from the old batteries. The coils are black because it’s likely the corrosion tarnished and ruined the nickel plating. What a fascinating movement.

Uber cool one!

Great restoration of a fascinating watch 👍, Isn't it strange that someone would leave the batteries in when they are so easily removed?

That's one weird clock face :)

The watch makers of the 60s & 70s had no fear when it came to case design. the generic watch of today is pretty mundane. Great video. hope your health is improving. 👍

Vinegar is a rather strong, acid pH 2-3. If you use vinegar to remove alcaline salts residu, you have to neutralize the vinegar with baking soda, since the vinegar will also attack copper tracings.

Awesome video mike!!!! Well done and I’d wear that watch a lot. Thank you for posting. Great choice for the bracelet!

Absolutely fabulous watch, great job with what you faced in restoring it. keep on the mend and stay safe buddy

super video

I'm just beginnng to view the video, so more later, but that watch should have been worn by Victor Bergman, Science Advisor (Barry Morse) in Space: 1999. It's out there! And when you magnified the gunk in the battery wells, I guess it was also "in there" ! Lol. Watching till the end now....

i loved the piano music wanted to hear more apart from that the watches look fantastic what do you feel about the the drum watch i've been wearing one for the past 3 years changed the battery's once watching the numbers turn is still fun it's a skmei drum watch not expensive at all but i like it

Wow that SAYTOKO looks like it's just come off of a old Star Trek set, actually quite a few do. Is that because you like the style, or just how they came? They're all awesome by the way!

Mike, great vid. I'm into vintage computers, and we tend to treat battery damage with a little bit of white vinegar (as the battery damage is alkaline) followed by Iso Propyl Alcohol.

Was that jewel catch that broke , not already open when you were prizing it , but trapping it with the peg wood that made it break ?

:) Time for a cuppa, I'll visit the rest later :)

i did manage to get a new crystal one of these Sicuras, like the one you showed, do you want me to dig out the source?

There is a potentially unique perspective on a "pin pallet" fork... Theoretically, there will be less contact area between the escape and pallets... but only if the pins are perfectly perpendicular to the escape wheel faces.

Would a dremmel and some slightly abrasive attachments not help you ?

As the leaking 'goo' from a battery is alkaline, the way to get rid of it is to use an acid, such as vinegar, to neutralize it.

the only watch youtuber that brings value content regularly - keep it up & congrats Mike

Another great video Mike, excellent mate, i'm happy you are ok, light circuits after a leek not easy, wold like to have a look inside a jump hour, but i really would like a micro rotor they look amazing lad, cu next time Mike. D🇬🇧

Good one Mike, difficult to really sort it when you can’t take the hour and minute discs off

Just picked up another Soviet Sekonda lol Seller dropped price down to £12 and I had to have it as its an unusual date only Slava 2428 manual wind twin mainspring... so much for cutting back on vintage stuff lololol

Not sure if this works for watches but some distilled water and baking soda will neutralize the battery acid while also cleaning the surface lightly.

Groovy baby:)

Could you use a glas fibre brush on the battery ports?

Tip for u an am sure that u know it 😊 Hot water is great for cleaning the battery dapry

Hi Mike I'm a long time subscriber I just thought I'd let you know that a very reputable Ebay seller in Australlia hnco (29016)currently has a similar Sicura for sale in case you need to source parts

Shame I missed you at the fair, next time!

Apparently Sicura bought out Breitling back in the day. So maybe it is more valuable than you thought.

Danish-blue batteries, yummy...

Astonishing how the jewel wound up in the rodico and you had to make "rodico pizza" to find it...and it's ALWAYS the last place you look! Is the Universe against us? Lol. I really enjoy that you always show the difficulties. I wonder if the Buler watches are more popular than perhaps they should be due to the homophone with "Bueller" - as in "Ferris Bueller's Day Off", the iconic "High School Senioritis Delinquent" film of the 80s, filmed in Chicagoland, USA? Have you ever seen it? Sir Paul McCartney has reportedly said that he disliked the inclusion of "Twist and Shout" in the film because of the use of brass instruments, at least according to Wikipedia. Most of that film's > $70 million gross take was in the US and Canada, but in a way, at least one of those watches would have looked good on maybe Cameron's wrist....he falls in the pool...fakes death...but his watch keeps going...."Ferris, You're my Hero...." Lol. Whatever the reason, I lived in Chicagoland at one time in my life, and having a Buler jump hour wristwatch would have been very cool indeed. "What kind of watch is that?" "Buler....Buler....Anyone....Anyone?" Cheers Mike and stay strong. You've got a wonderful collection there.

i have it

The band was a good choice.

heftig geiles Teil

That is the worst battery leaking damage I have ever seen.

I wish I could remember what video I saw...there was a company that was unable legally because of some law that had been passed, to go to a jeweled escapement! ...oh, it was Chronoglide I think! Anyway, it sounded like this watchmaker was stuck with pins until a late date. Maybe someone can elucidate more?

I’d wear it 😂

Hi Mike great video Good to see you back in the swing on an unrelated note I was wondering on your thoughts on watch cleaning fluids I have been lucky to purchase a vintage benray fully working and not sure if I should use l & r fluids or Elma that you dilute with water what are your thoughts best wishes David.

I absolutely hate pin pallet movements with a burning passion

That's one wacky special piece. Does George Jetson know you have stolen his watch collection? 🙂

Too bad they don't make so many jumphour watches nowadays. There are some ones that look like a jumphour. Except that the hour doesn't actually jump.

Try using carbonate water it breaks alkaline up next time without damage to paint .

How much is it?

Redroosteruk on EBAY for the spring got some the other day

You act like you never cleaned battery corrosion/acid before. Just use alcohol and vinger and qtips already and rub it. Why are you acting afraid of it and picking at it with metal things like it will do something if you are not careful? This is simple stuff to do and take a few min to clean ip really.
