re: OT Watch Thread: How accurate is your automatic?

I haven't tackled this yet. Quite frankly hands frighten me.

Hands truly aren't an issue and you honestly don't need a press or a hand remover. The little push sticks for hands are find and the as long as you use some paper or plastic with a V (Bergeon makes them) and gently pry them up.

The easiest thing to ease the trepidation is get a cheap Seiko like a SNK800 series, I bet there is a youtube vid to walk you through that exact watch.

Overall it is pretty easy but I felt the same way until I did one.

1. start with a run down mainspring
2. set a day/date or date watch to midnight you don't have to worry about that if it is a no date
3. remove the case back
4. release and remove the winding stem
5. remove the movement fixing screws
6. flip the case over and the movement will slide out
7. remove the hands
8. remove the dial

reverse the process and use silicon lube on the gasket and a tiny dot on the crown threads

I test for waterproofing but I have a knock off of a Bergeon 5555. I dive so I test before taking any watch diving.

I remove most case backs with a sticky ball but have a Jaxa for stubborn ones and knock off case back dies for Rolex and Panerai, you can get the Breitling ones too.

The only thing I have to look up for a new to me movement is how to release the stem. They vary and some are specific in you don't want to rotate them more than X degrees.

Have some Dial Dots on hand those dial feet are often brittle and is the reason Dial Dots are a thing.

A set of Bergeon or similar (ie much cheaper) screwdrivers

A quality set of tweezers you can buy Bergeon, Dumont or Horotec but I have a very good set of Swiss made Ideal-Tec for about 1/4 of the price of Dumonts.


In the end just take a stab at it, that's what I did the first time. Once you have done that it is time to do the Watchtime.com online watch school. It is very well done $75 for each of the three levels plus tools and movements of course but there is nothing cooler for a watch geek than to actually disassemble and reassemble a movement.

Update.

The 7S36 is +28 sec/day out of the box.

Love the look of the orient mako. Might just pull the trigger on it. Had a seiko skx007 for about a year and have had no complaints.

Have a Rolex Daytona and Datejust. My Daytona is probably +5 seconds/day. Datejust is more like +20 to 25. Need to have it serviced ..

Casio waveceptor....downloads the time from the atomic clock everyday.....nothing else is more accurate.

Same. Solar powered atomic Casio G-shock. Gets the official time every day. Never needs a battery. Never needs adjusting.

I think it was 90 bucks and I love it.

Have a Citizen ECO drive that's almost as clever. But not quite.
