Restoration of a Classic Vintage Rolex - 1972 Rolex GMT Master with 1570 movement

[@andywilliams4887]

Watchmakers are like surgeons in my book. They can bring things back to life.

[@richardperrettwatchmaker]

Hi Andy... I have much respect for surgeons as the stakes are normally way higher when they work! Thank you so much for the feedback. Richard

[@calsurflance5598]

Excellent and soothing video. I was an aircraft mechanic for almost 30 years, have worked on Ferrari’s , Mercedes, Jaguars, Marine engines,antique steam locomotives, and even a Land speed jet car, so I can appreciate the attention to detail. But the work you do on the inside of a Rolex leaves me in awe! Well done!👍

[@richardperrettwatchmaker]

Hi Calsurf ... those are some nice machines you used to work on. George Daniels (famous watchmaker) was also a very keen car enthusiast as of course is the genius Richard Mille! Thanks for the feedback. richard

[@keithpruden8634]

Very reassuring to see my watch being handled so well from beginning to end Richard - first time any of my watch servicing has been videoed like this. Your regular calls on progress with the job were also reassuring and very much appreciated too. I'm glad now that I didn't try my Mole Grips and WD40 approach on this one, I'm sure I would have managed but perhaps without your finesse! Looking forward to receiving the watch. Thanks again for the fine job Richard, Keith

[@richardperrettwatchmaker]

Thanks Keith! It's winging its way to you as I type this. I am lucky to work on lovely vintage watches like this but having good clients makes it so much more pleasant all-round so thank you so much for being one! Thanks again, Richard

[@smr32061]

That GMT is in excellent condition for it's age. As always, great work! Watching you work is akin to watching a surgeon perform a delicate operation.

[@richardperrettwatchmaker]

Thanks Stephen ... I figure I would shake a little more with blood all over the place and my patients vital signs bleeping from the monitors in my ears. I respect surgeons greatly and am not in their league! I do know way away a Rolex though! Thanks for the feedback. Richard

Such a joy seeing you work your magic! I often hear people saying the Rolex movement is undecorated and ugly. I think it is a beautiful masterpiece that performs year after year like few others regardless of cost.

Grail Watch for many. I was underwhelmed by the plainness of the movement, when you look at some of the other watches out there. With far more decorative movements. This looks like it’s out of a Seiko 5 from the 70’s 😱 Great Work on the service and regulation.

[@thomasgibson4619]

Great video, thanks. One of your screwdrivers seems to be a bit magnetic, it picked up a couple of screws. Would that affect anything in the watch?

[@richardperrettwatchmaker]

Hi Thomas .... well spotted! Not often magnetism is helpful inside a watch! In this instance it's unlikely but I would not be using a large magnetised screwdriver anywhere near tthe hairspring or I might give myself some unecessary work when it comes to regulation! Thanks for this feedback. Richard

[@Zeeraha]

It's not Richard's fault for using magnetic screwdrivers, thus it is Rolex' fault for utilizing screws which can be magnetized.

I try and remember that in reality the stakes are not too high when compared to those engineering feats accomplished by my brother in law during his tours of duty as a bomb disposal expert!

Wonderful videos brother. Former Green beret who has found a new calling in life with the fascination of horology and watch making. Im 35 and looking for some solid advice on where I could learn the trade/art.

[@richardperrettwatchmaker]

Hi Nicholas .... there are colleges that you can go and study at but it is normally full time and vert expensive. I just started with cheap watches and practiced and practiced and practiced. And also studied a lot of horology theory. It took me about 3 years to get my error rate low enough to work on other peoples watches and 5 years before I tackled my first Rolex. I advise you just start ... buy some screwdrivers, a loupe and some tweezers, get a bunch of cheap seikos off ebay and start taking them apart. Hope this helps and good luck! Richard

It's strange that something that I think if I tried it would be incredibly frustrating and tedious, should be so relaxing when watching a professional do it.

[@MyRetroWatches]

Really liked this one . I’ve never been inside a Rolex and would be fearful but then once you took the dial off it looks straightforward enough. Your style on this one was very Red Dead ! Why would you change the mainspring? Just good practice or was it in your professional opinion past it’s best? (Genuine question) Really like the idea of using the tweezers as a steady on some of the trickier screws and might try this for myself although I don’t use those bent tweezers.

[@bc9054]

Just curious as to why you didn't have finger coverings on when you were taking the hands and dial off? Is there a possibility of oils staining? I am new to this and just trying to learn. I love the videos you produce! Thank you for sharing.

Nice movement to work on

[@shedlock2000]

That was very interesting and nicely filmed -- but I have questions: How do you install the arbour on the barrell and feed in the mainspring (and how much oil does the mainspring have)? How do you adjust the microstellar screws on the escape wheel for accuracy and how much messing about is required to adjust them in 5 positions? How do you set the pinion weights for the escape wheel pinion and how do you set the bridge heights? I saw that you released the mainspring tension, but exactly *how* do you do that? It was very interesting to watch the service. I am assuming you also replaced the gaskets -- did you also replace the crown and tube? Thanks for all of the information and excellent strip-down and re-build -- I appreciate the video (can you do a longer one on the same movement)? Finally, can I get your watchmaker thoughts on the difference between the 3075 and the 1575 (gmt) in terms of robustness and durability, please?
