Seiko Motorist crown?

[akable]

I am hoping someone can assist in helping me find the part number for the crown from a Seiko Motorist.

This was a models from the 60's but unfortunately I can not read the case number on the back from the images provided.

I purchased this one a couple of weeks ago and I am still waiting on it turning up, but here are a couple of images from the seller.




As you can see the crown is smaller and marked SW, where it should be plain and be much closer in size to the case notch. Here is an image from the web I believe shows the original crown.



If anyone has any info on tracking down one of these it would be great.

Surprisingly there is another one on these on YJ at the moment and it lists the case case as J14108E. Looking closer at the sellers image on my example this does seem to match.

The one on YJ at the moment looks like it has the original crown but this is heavily worn like the rest of that example. Strange how you do not see a model for ages and then a couple turn up just a couple of weeks apart.



If anyone has a casing guide that lists the crown for the J14108E it would be appreciated.

I might have one of those crowns here or not too far away.

Can you take some measurements?

Need the OD of the knurled section and a shot of the underside (to confirm stepped or not stepped).

I'm guessing the correct crown is the non SW marked crown as they were generally only for early KS/GS. For some reason SEIKO made many more of these crowns than the generic crowns so they were often fitted at service.

Thanks for the help Adrian.

The non-SW crown is the correct one, unfortunately the two photo examples I showed were not mine so I can not measure these to get an exact size.

Once my one turns up, hopefully towards the end of the week, I will take a rough measurement of the crown notch in the case and some shots of the fitted crown and case side that may give some more details as to stepped or not.

With some luck I am sure that something closer to the original will be able to be located as the current one does look out of place.

Here's what I have here, but might be able to get other variations.

55W12 on the left, 55W02 on the right.

If someone can get the part number I can check my extensive inventory.  If not OEM Seiko I might have it in a vintage contemporary generic version from Borel or Jewelmont.

Wow, sorry I missed this in all the confusion over Ozzy Pouges. My books unfortunately don't cover this model, but all is not lost! I now a bloke that may be able to help, although it will take a few days to a few weeks as he's a grumpy old sod that doesn't like the internet

The watch has turned up and I quickly measured the notch in the side.

This is 6.2mm wide, so a 6mm wide crown would be the largest but looking at the original crowns in a couple of the shots above I would estimate the size to be about 5.8mm

Here are a couple of quick and dirty phone shots of the watch and crown.

This may help to narrow it down

Sorry about that Adrian, hopefully they should be displaying now.

The current crown is 1.9mm thick and 4.5mm across, so the 5.5mm sized ones you suggested would be great.

The 55W02 seems to be the closest to the original but my only concern would be the height as it looks quite thick compared to the shots of the original version. 

[Adrian-VTA]

I think the W02 is a near match. I think maybe half a mm thicker than original?

I'm in the city on Friday and will go through the ancient drawers again and see if I can turn anything up.

Would it be a "W" crown? As the watch is not marked as waterproof, wouldn't an "R" crown be correct and may also be thiner?? Just my musings and base on no real facts
