Amateur regulation of SKX/7s26

[HobokenRolex]

My SKX 007 never kept very accurate time - it was maybe 3 min slow per day. Whenever I wore it, I'd just set it ahead by a few min. I would typically only wear it during the day for a few hours (and only 1-2 days per month) so it never bothered me. However, I figured that I could - maybe with luck - get it more accurate after watching YouTube videos on adjusting the movement. $30 in cheap tools, with a few attempts, and it's + 30 sec per day. I'm happy with that and had fun working on it. Here a pic of the movement.

Well done! I was going to try that with my new Turtle, but it's only + 8 sec/day so I'm going to leave it.

Looks like to fun to try at least

Thankfully my SKX007 is only +5 per day...
But I just looked and it was overall after 5-6 days +30.
I tried to hack it by slight back pressure on the crown but it just kept on ticking...not much one can do in that situation.
If I was going to regulate my watch I would buy a Weitchi timegrapher, but that is $150, almost the cost of the watch itself, and then other tools on top of that, it just isn't worth it for me, and I don't mind the daily variance so much.
But maybe one day when I've got more time on my hands

I don't know how you can properly attempt to regulate your watch without a timegrapher, because you need to adjust both the beat error and the beat rate to make the watch more accurate.

Cool thread to start.

After opening the caseback, so you need to replace the caseback seal?

Or will it be okay?

Lol-x, good point about the timegrapher for proper regulation. I just adjusted the lever with the + and - until the time gain/loss was acceptable. I only wanted to spend a little money to see if this would work.

schoolboy, I did clean and regrease the gasket (it didn't appear to be dried out). I'm sure a new one would have been a better idea, though. I'll probably go swimming with the watch at some point so fingers crossed there is not a leak.

My vintage King Seiko 56xx watches have a small screw between the lugs that hides a second small screw, which can be used for simple regulation. I haven't needed to try it yet, though, as the three of them are all keeping great time.

Only if it is damaged. You can also use a marker and place a slash on the case/case back before you remove it. Then put it back on and line it up at the same slash marks. That way you will know it is at the same tightness as before and should be water tight.

Cool deal, I’ve always wondered this.

Let us know how it goes and thanks for sharing.

Super cool, never heard of that before.

Cool, thanks for the info.

Nice!

Mine is running at a delta of 40sec, pretty good time but gaining significantly in just one position. I adjusted the slightly decentered hairspring but still. Would have to take it off the bridge and put it on the poising tool...
