Stupid question!

Hi,

This is my first post, hopefully not my last!

I have a Seiko Seahorse 'Waterproof Diashock 17 jewels' that I recently got up and running - "left in a cupboard for 20 years", but I don't think it's quite right.... it runs perfectly well and I can set the time with two notches out on the crown, but...

Shouldn't the crown rest flush with the body of the watch and should I be able to set the date separately to the hour/minute setting?

The watch looks and runs great but it doesn't feel right, or am I looking for functions that don't exist?

Any help would be appreciated,

Thanks in advance.

Most Seiko,s the first position out is for setting the date and the second position out is for setting the hands. The crown should be flush with the case after settings are completed. Some are push fit and some are screw down crowns.

Is it definitely two clicks on crown?
Seahorse I know use a 7625 movement which, according to my sources, is only one click. Date is set by moving past midnight until it changes then back to 9pm then again past midnight etc.

If "Plato" goes to this web site http://www.seiko.co.uk/customer-support/support/instruction-booklets

& enters the caliber in the search box he can download the instruction manual.

Not sure if the early Calibres are in that link.

Plato - there should be 2 four digit numbers on the bottom of the dial, e.g. 6608-8010.

The first is the calibre number, which should also be on the movement and the second the case number.

From the calibre number we should be able to find if this has a quickset date, but I would suspect it doesn't.

Photos are also helpful!

Thanks all for your interest, the full model number is 6602-8990. I did try the Seiko link originally but I couldn't find it there or online generally... all I can see is that the crown on similar watches seem flush but others don't? It's not a 'screw down' and I don't think it has any dirt in the way (I removed the movement to replace the crystal).

I'll add some photos as soon as I get to it on the weekend. I'd rather not do any work on it if there's nothing wrong... I have other watches to practice on first... I'm very new to horology so excuse my ignorance too!

6602 doesn't have a quickset date, so you have to wind past midnight to 2 or 3 am, then back to 9 or 10 pm, then forward again to set the date.

It's possible that the stem is not installed correctly in the movement. Try pressing down the release button to remove and re-installing it.

Thank you both again for your assistance.

The wrong stem seems to be most likely as I have tried reinstalling it again with release button fully depressed. I was quite happy with the experience gained from replacing the crystal but getting the stem right will be good practice too!

I have another Seiko (an automatic 7005B, I think) that I'm certain that just needs a strip down and service to get right so I'll get stuck into that one first.

All the best,

Geraint.

      Chronograph Pusher Rod for EB8371-67 Snapped and Stuck in Button. Can't Unscrew.

      By watchweasol · Posted

      Hi. Yes I get it , the slot in the end I’d to allow you to screw the button on whilst holding the pusher shaft. To remove the pusher tube you will need a tool such as the one shown by Richard. I think Ali Express the Chinese Amazon has replicas of the Horotec system for a lot less money, how effective they are not having had to use one. But as you said the way to go is complete removal and replacement, bodging it up will  lead to a repeat failure

      30T2 adjustment of timing washers

      By JohnR725 · Posted

      One of the things that I've been bothered with lately is timekeeping? For instance a 90-year-old pocket watch what so to timekeeping was it supposed to keep? They publish railroad timekeeping but I don't know how well normal non-railroad watches were supposed to keep time. The reason why the question comes up for me is I spend a lot of time at work adjusting watches to keep really really good time  because I have to please my boss where as when the watch was made I have to wonder what kind timekeeping would've been acceptable. After all they typically didn't have timing machines 100 years ago and they were timing and six positions certainly not for the non-railroad grade watch. On the other hand I do get paid by the hour so maybe I shouldn't be concerned of how much time I Spend trying to make everything keep chronometer timekeeping almost. Citing a Delta of 40 seconds for a 90-year-old watch is quite outstanding.

      Is this pallet fork over-locking?

      By JohnR725 · Posted

      That's an interesting question which I don't think I've seen explained anywhere. But I think the problem will go away just about instantaneously. In other words the  coating is really thin and it should go away almost immediately. So the problem should resolve itself extremely fast.

      I experienced that different types of shellac and their ages are affected differently by IPA. Sometimes the shellac dissolves in a few seconds and sometimes several minutes are required. Nowadays I never let shellac come into contact with IPA. It's a hotly debated topic here on WRT if you search. Like John, I don't think you need to worry about the weight of the shellac, but instead that it might start rubbing against something. When I learned how to adjust pallet stones, I tried documenting my experiences in this thread. Hopefully, it can help you. I personally don't believe in the idea of abrading the epilame before oiling so I don't think you need to think or worry about it. The only time I've heard anyone mention this is Alex on the YouTube channel Watch Repair Tutorials but actually no one else. I'm not saying it's "wrong" just that I don't think it's necessary or adds anything.
