Well, I did the swap and I can report that I did not have any issues. The movements appeared to be identical apart from the embossed movement number on the rear metal plate that I also swapped. Brother in law is going to be very happy with his repaired watch. Tip for everyone, do not leave batteries inside watches after they have stopped working as they will leak and corrode the quartz circuitry.

Found this: https://www.thewatchsite.com/threads/movement-interchanability.163186/ The general consensus is that they are exactly the same apart from the rear plate that can be easily swapped if desired.

Thanks, I have seen that information but do not know how accurate it is. I wanted to hear from someone who has actually done the swap between the two.

Hi, Has anyone actually replaced Seiko 7T62 with a YM62 movement? Any differences encountered between the two? YM62 is much lower cost for me and preferred if at all possible. Thanks in advance.

You're not wrong, lovely watch.

Thanks guys for the input. I do have some old Ricoh balance wheels minus hairsprings that I can use for practice. I will report back on how it goes.

Well, I have the Jacot tool and have made a burnisher (3mm x 3mm graver with one side rubbed against a 600 grit diamond stone, held in a pin vice). I need to take the pivot diameter down from 0.088mm to 0.078mm (measured with a mitutoyo 0.001mm micrometer). That's a hundredth of a mm reduction. I have watched the various videos on YouTube regarding Jacot use and I am making an appeal for help to you guys with experience of using that tool. 1) Did I do right using the 600 fine diamond stone to make the burnisher finish, or should I have gone finer? 1200 grit? 2) How much burnishing wi

That's a really nice finish. What type of abrasive paper did you use? Manufacturer and grade?

Completed the watch today. Seiko Sportsmatic 411, 7005-8016P, lemon dial, eBay find, originally bought in 1971 in Singapore with original guarantee card, no web sales back then. Fully serviced and running very well. Very happy

Finished case. Still has a few minor marks but. I think if I went further then I would start losing the case lines and sweeps. In any case this watch is 50 years old so I don't want it absolutely pristine. VID_20201231_183617828.mp4

Hi, Just wanted to share my experience of radial brushing on a Seiko 7005-8160P. I built a little jig using a block of wood, plastic case press, and Wood screw. I think the pictures are quite explanatory. The red tape was used just take up the slack. Using a junior Jigsaw blade with some 600 grit paper wrapped around it and short 5mm strokes back and forward as the case is rotated slowly. Using the long slot I made in the screw head as a guide. The height of the screw is adjusted so that the Jigsaw blade is flat against the case and not at an angle. It's working pretty well. Will post a pictur

Interesting watch, how old is it?
