@@islandwatch many brands use 904 steel. GP Laurrato chronographs all use 904 steel for example. It is not harder to polish at all. It is harder to machine. It does not buff to a higher polish finish either. It is simply less corrosive as you state. Sounds to me they there is a lot of conjecture in your video which will only serve to mislead and confuse people. Please research further to validate.
I vary rarely coment on videos but in this case I must, I have been watching your channel and I'm very impressed your comprehension of the technical side of watches is very impressive, great channel and I have been recommending it to my watch friends although you don't talk Vintage you have made me learn a lot about newer watches.
Thank you for doing that! I don't talk vintage at all, since I really don't know it. My background is in what I sell, but moreover, it is in engineering and the application of science in a watch.
I came across one of your videos today having only been familiar with watches in a fashion-sense. I've never become so interested in a subject so quickly because of your knowledge and delivery. Thanks!
Great video Mark! There’s a lot of different sources and mis-information on various forums, so it’s wonderful to see you dive into a lot of the details.
An example of blasted and polished is the SEIKO 5 SNZG15(black fabric strap) the side of the case in between the lugs have been polished. Barely noticeable but it's there. My guess is the reason is not for looks specifically but rather for avoiding dirt and other debris to lodge there. I really like the watch and learn series!!! perhaps, could be a good idea to make a video related to dials, dial materials, functions, lume types, etc. cheers!
keep up the good work, even as a minor watch enthusiast, I'm still learning new tidbits and facts about the watch industry / physical build everytime i watch your video!
Great Vid I've seen you on TGV very knowledgeable If I'm correct you're a engineer. This takes watch collection as a hobby to a all new level!!I find every nook and cranny of every watch absolutely fascinating!,Now armed with this new knowledge of the basic metallurgy of watch cases I. Fascinated beyond belief!!,Again thank you for passing on the priceless knowledge!!!,ALL my best Boston USA..
Thank you for another very good video. I have a couple of questions: - On cheaper watches the description "gold tone" is often used. Clearly it is intended to imply that the "golden" appearance is not real gold. However, the "gold tone" Brooks Brothers branded watch I bought at a thrift store look....well, great! What IS "gold tone" material? Is it a plating, over stainless steel? - Can you recommend a good polishing compound for stainless steel? I know you used the term "jewellers rouge": is there a brand that is generally highly regarded? I assume that the silver polish that I have for my silver items is not suitable for stainless steel..
Again, a really nice episode! I like that it's stating facts instead of simply opinions. Which isn't a bad thing, but these kind of video's make me, as a customer, more knowledgeable and better informed so I can form my own opinions better. And also it makes me appreciate the product more. (if it's a well made piece that is....) Keep up the good work and I'm looking forward to the next episode. Cheers
I know this is an "older" video - but I'm wondering if it is possible to use an automotive detailing ceramic coat product to further protect the watch surfaces. I have heard of many people using it for such things as protecting watches, sunglasses, even cheap safety goggles. It seems to notably reduce wear and tear. Thoughts?
I'd love to watch a video on the various components that make up an automatic movement and what their function is like springs, escapements, balances, rotor, and jewels. Also, do you think Orient will ever produce a mid size Bambino, 36-38mm, with either an 18 or 20mm lug width? They seem to listen to their customers and make accommodations as in their USA rays and makos. Just a thought. Thanks!
Hello! Have you checkout out the other watch and learns? There's one ( I think #3 or #4 where I talk all about jewels, take out a balance, show you a lever escapement, etc. . . As far as Orient, I doubt it. They finally released a V4 bambino, and they went UP in size, not down!
It would be awesome if you did a video on watch straps, their differences, and their history. Because I was looking into that the other day, and it's actually quite interesting. I'm gonna buy a shark mesh for my diver.
My friend your video has been very useful for me. I wanted to know from your experience, which finish was more reliable toward scratches? Furthermore, IDL if you have any Titanium Grade 5 watch, if you do, which material you find it more reliable toward scratches? Thank you very much.
Hey Mark. I have a vintage Omega date watch in 10k gold fill. But the very inner corner portions of the lugs have wear so bad that I can see holes in the lugs themselves with a magnifying glass. I can actually see where the inside of the lugs are hollow and have some green corrosion of some kind inside the lugs. Does this make sense? Thanks man.
Hey Marc, another great video. Off topic, but I have noticed that some movements the rotor moves easier when the watch is moved around. Why is this the case?
excellent video series I really enjoy the content and hope to see more and more of it I really hope that the channel grows and you get the following you deserve
great video, on a topic i've wanted to know more about for a while. sidebar: i always thought more cookware was magnetic than not, esp. due to the rise of high end induction cooktops that require magnetic materials and high end cookware often being stainless steel.
A Watch and Learn about different movements and different automatic and mechanical watches from beginner or entry level to more advanced and expensive would fun to watch.
Can you make a video showing the different textures of tegmented steel, diashield, duratech TIC, DLC, duratect MRK, ice hardened steel and duratect alpha?
I’ve learned a lot from long island Marc I change my own bands etc good channel I also bought some beautiful watches from him I love vintage retro style and I got some good deals
mountainhobo DLC is "Diamond-like Carbon," it's a (usually black) layer of carbon that is very hard and can be applied to the outside of the watch. DLC is a material, whereas PVD is a process that can be used to apply it. I.e. DLC is often applied by sticking the watch case in a vacuum-sealed oven and pumping in carbon-containing gas that deposits DLC on the watch.
Shawn Byron Beckett Thanks, Shawn. Yes, I have read up on it since Marc mentioned it. It seems also that the quality of the case material matters when applying DLC. Some cases appear scratch proof, while others still scratch due to the softness of the base material. Interesting technology.
mountainhobo You pretty much found it out yourself. Your hardening processes are DLC, whereas PVD is not. DLC watches 'generally' won't scratch, and as Shawn mentioned, DLC is a materal whereas PVD is not. You can PVD gold (well, not gold, but colors like gold), silver, blue, black, red, etc. . . DLC is always BLACK.
I would like my Invicta gold colored model number 22132 color changed to the very last black colored watch you showed in this video. that dead black P.V.D. Could you please leave a comment how, were, and approximately what's the cost, and can it be done on this style watch?
Bead blasts than Pvd coated , polished then Pvd coated or brushed and then Pvd coated, witch one do you think is most durable ? I have several Pvd coated watches and the only places it has worn off is between the bracelet links, so far that is
It's a loaded question, as it depends on the finish quality. Assuming all have the same thickness, they will all be equally durable. I would say satin would 'hide' the most abuse though.
I dropped my Seiko Sportura chronograph on an Apple MacBook. No scratch on the watch, a dent on the MacBook. I always bring it up on Seiko forums and get thumbs up from Seiko themselves. :) Yo! Thumbs up from me, too.
@13:45 PVD - I understand you to mean the PVD coating is the case metal vaporized and deposited onto the case where it hardens and re-solidifies. Another watch youtuber - federico talks watches - claims PVD is a plastic coating. Can you confirm which it is? Link to Federico's claim: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1GusPQvaXuA.html thank you for making these very articulate videos, Mark!
Thanks for the question. Just watched it. I think if you asked him if he really means "plastic", he would tell you that he didn't mean it in the cheap, injection molded, sense. He means its a coating, that''s not perfectly bonded to the case, which is correct. That is why your better PVD coatings are much thicker than your lower grade ones. So, if its very thick, and you get a light surface scratch in it, the base material will not show through.
PVD? This is outdated really. DLC is better. Watchmakers need to turn to premium gunmakers already (Sig for instance) to learn how to do a much better coating of their watches.
Alexander Holding It concerns me because you posted it publicly, not as a private message. You put it out here, therefore I have a right to comment. Treat people on the internet as you would if you were face to face with them in public. I'm done commenting on this.
