Your information is incorrect. I am not an authorized Seiko service center, I am a authorized Seiko dealer and Seiko USA does indeed sell parts direct to its dealers. The point however is that a quick login to Seiko's website shows that  the genuine Seiko crystal, 310P03HN02 is not obsolete, and in fact Seiko USA has over 50  in stock.

WOW a jump dial !!!!!!!!!!!!!!!!! never saw that before on Timex.  is there a date code on the base of the dial?

Hi   Apart from the advise al ready given there is Esslinger, Timesavers in the states perrins in canada  and cousins in the UK best to have a look at each supplier and make your choice. 

Hi All I'm a beginner and this is an AS1951 which I got working after a clean and oil.  I didn't remove the mainspring.  I have only a few few sizes of winders and usually have much difficulty with them.  I did remove the barrel lid and ran it through the ultrasound.  I then added a few dabs of  8200.  The jewels got 8000 and the pallet stone 9415 (all Moebius). The amplitude is better than I usually get and the rate is ok.  How would you read these pictures?  Is all ok?  What are all the stray dots?
