Longines Master Collection Disassembly (ETA 7751) 

How in the world does a screw come completely out in a tight movement like that, then find it's way into the gear train? Unreal. FYI: I just purchased this watch and am looking forward to it's arrival. My first "Luxury" watch. 😎

Well, they don't call it complications for nothing. Very nice job sir!

Now I understand why I paid $450 to have my Master Collection serviced. Of course my watch was running but was losing time after being worn daily for 8 years.

I have this watch with blue dial. Works like a charm

This is definitely the older model without the column wheel chronograph

Nice job but the watch it is just a replica. Not an ordinary fake, a good quality replica but still a replica. It is difficult to spot it unless you are a specialist or own one. On the back, the moving part where it is engraved the brand, on the original watches the logo is cut and you can see through the logo, on the replica this is missing. Sorry, but you should mention that.

That's great to see you are service the watches so well. You are so professional. I like it.👍 Longines Master Collection triple days moon phase has 3 versions caliber 1. L687.2 2. L687.2 (Column Wheel) 3. L687.5 Which version is better? Why?

Excellent video, thanks, but could youpooibly tell me how you remove it from thecase? Does it come out via the front bezel?

How did you removed front glass without removing chrono push buttons.

Great subscribed.

Awesome! In your experience, which watch brand model has little to no plastic parts in their movement?

hello congratulations for the video, by chance you have a spare part, of the wheel of the day driver spring, I am sending you the photo of the broken part

Very komplikatet Watch

Hello question: was the moonphase held on by any screw or was it being held down by the dial? Thank uou!

Super vidéo ! Comment avez vous sorti le mouvement du boîtier ? Merci

I bought that watch a year ago and it has gone to service twice already. The first time because water was coming in and the glass inside was getting wet. The watch was sent both times to the same service in the UK in London What are the company's rules? Is the warranty extended and starts from the day the service is performed. The second time the stopwatch did not work properly, it did not brake and did not want to return to the starting position. Are these problems common with this model or am I just out of luck?

Thanks for this video, but how do you remove the back cover at 1:45 ? Is it screwed ?

Are the gears on the back made of gold?

This is fake?

Dont try this at home.
