Hi there,

Hi all.

I have a mint condition Seiko Prospex Marine Master 600m Spring Drive (model SBDB001) which I bought direct from Japan.

The watches Titanium bracelet is still perfect, but the clasp needs replacing as the small pin that the main lock uses (where you have to squeeze the buttons) broke off during use. So now the only thing holding the clasp closed is the small secondary locking flap. The Clasp has the micro divers adjustment with a ratchet mechanism which is operated via the clasps secondary lock and has Titanium + Stainless Steel written on the inside part.

I'd also be interested in a price for the replacement Bezel kit which I've seen before for sale on watch forums.

I've seen that the Seiko reference to the SBDB001 is 5R66-0AD0 and I found this website which lists the part references:-

Therefore I think the clasp is Part D302DG-BK00
And the Bezel is Part 86313284

Can anyone help as good old Google isn't turning up many answers.
