Hi WRT,

I'm totally new to the world of watches. I've had this Seiko SRZ392P1 for a couple of years. I recently took it to a watch repairer to get a battery change and it seems he has lost a part and managed to scratch the backcase in the process. At the moment the crown won't lock in place/wind, soooo, I'm curious to learn how to replace it myself. How would I identify the necessary/missing part?

So sorry to learn that a watch repairer can be so incompetent.

Looks like he lost the movement ring but the crown looks like it can be screwed back onto the stem. The stem doesn't look like it's broken but to screw it back on can be a little tricky as stem needs to be removed first. If you look carefully, there is a small lever near the stem with a little dimple on it. If you use a sharp tweezer to depress the lever, the stem should be released and can be pulled out.

With the stem in your hand, the crown can be screwed back on. If it still feels loose, a tiny drop of Loctite can be used to secure it.

You can probably check if there are any videos on YouTube to help you out. A picture is worth a thousand words, but a video is worth at least a million.

Good luck!

To save the dial and hands, google watch hand removal for relevent tutorial.

We need a clear close up of the movement for possitive identification. Your best just replace the movement with a new one if available. I am not sure if parts to this can  be bought.

Good luck.

Here is a video on how to refit the crown.

The OP did not say whether the movement is working or not. So I assumed that it's still working. 

As for the missing movement ring, Cousins has generic spares that can be cut to fit the case but it comes in a bag of 100s. So I'm not sure how you can solve this problem. Maybe if you have a 3D printer, you can print your own.

      Don't stop there, those railroad spade hands want to be polished and re-blued too!

      Crown and stem size

      By MKUltraBlack · Posted

      The Wizard did it 👌 I got the case back and went to take the movement out of the old case and broke the balance staff, went to 8 jewelers etc, all told me it would be a £300 service, had an old half watch (ww2 waltham) that I bought to try dial luming and put the balance wheel from that and as soon as I slid it into the palet, without even screwing down the balance plate, it started ticking 🙂 all working now, with balance and case all fine. Gonna get the case plated and re-line the box now. Thanks to everyone for their help and insight. Much appreciated 👌

      Staking punches

      By Simeon · Posted

      So, finally managed to snag myself a staking set from eBay. It's a vintage Boley and Leinen set and it looks a bit rough - this is OK as I didn't pay a lot of money for it. Some of the punches look like they have been used to drift out truck wheel bearings! Anyway, I am planning on cleaning up the punches (soak in Evaporust followed by chucking them up in my drill and polish with wire wool and oil) plus working on the ends with an oil stone /Emery cloth to debur and tidy up. I will also make a new lid for the box and repaint the 'anvil' (this is the non-functional part of the restoration, purely for beauty 😉). Do staking punches come in a common size? 5mm? If so can I buy replacements / new to pad out and complete my set? I had a look on Cousins and they only sold complete sets, not individual punches so I am guessing that I would need to find odd used punches on eBay rather than being able to buy new replacements.  I haven't received the set yet so can't measure the punches but they look a similar diameter to others.

      Incabloc Spring Installation

      By HectorLooi · Posted

      The belief that only Chinese clone shock springs and not genuine Incablocs come loose is a myth. I worked on a ladies Omega a few months ago and being a genuine Omega, I was a little cavalier when opening the shock springs. The upper jewel was fine but the spring of the bottom jewel took flight when I swung it open.  There was a little gap between the chaton and the main plate and this was how the spring managed to slip out. Had a real hard time getting it back in, as the gap was so small. So now, regardless of whether it's a clone or genuine Incabloc, I always use a pegwood stick to prevent the spring from getting anywhere near the back of the hinge where it may slip out.
