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.

Some times dirt gets in and around the inside of the button and it packs tight, this will prevent the button from sitting correctly to the case.

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!

Here are pictures of the watch, I couldn't wait until the weekend.

I was wrong, there is only one click out. The photos show both positions, it doesn't look right to me.

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.

    • Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.
    • I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.
    • Get well soon Old Hippy, torn muscles.,  not good
    • Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.
    • If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
