Hi, all,

Just got a SEIKO 7016-8000 chronograph and some questions:
  1. Upon opening the case back, I cannot find any movement spring like the one we usually find in 61xx series. Instead, in the groove is case back gasket. Is this correct?
  2. What is the case back gasket part number?
Thank you in advance.

No case spring to this model, gasket is FH2920B03, hope this helps.
Thank you very much, Sir! I have guessed it must be a flat type gasket but no idea about the thickness and part #. Thank you for taking time to look at the part #, highly appreciated. :)

CousinsUK have them in stock, 2 for £1.50 plus VAT and postage :)
Thank you very much for the heads up, John. Just signed up at Cousins. At the moment I am using FH2980B01 as temporary gasket. It is a bit thinner than FH2920B03 because I can see the dial moves when I pulled the crown for setting. :grin:
