Hello All, I am new to this forum but I did look around it a bit when I was looking into watch tools and getting started. I have acquired a few Seiko 7009 movements to get some practice working with Seiko before I tackle a Seiko Sea Lion M44 that I bought. However, since I have several movements, I thought it would be nice to piece together two watches with the two cases I have. I am having some issue sourcing/identifying the case components. In the attached image you can see two cases. The numbers on them are 7009-875J (left) and 7009-8599 (right). For the 875J, I believe the crystal and the O-ring need to both be replaced but I cannot find a suitable replacement on CousinsUK. The closest I have found was for a 7009-8750 case, which has a chrome ring that I did not find when I took the crystal off this case. For the 8599 case, I found the XAC311.652 Sternkreuz, Seiko 310T49ANS0 on CousinsUK which seems like a fitting replacement. Additionally, I have several movements, but I do not have the movement holder rings used to settle the movement into the case. I saw in a post by @Waggy ( ) that he has created CAD files for the movement rings, but I was wondering if those rings are universal for all 7009 movement and case combinations. Even if those work, I do not have a 3D printer, so I was wondering if there is anywhere else I could source them.

Hello all, I am new to watches and have a beginners question. I have a Bulova 23, L8 witch needs a new crystal... I can’t find a parts or maintenance Manuel on line anywhere and was hoping someone might know which crystal I need purchase and perhaps a reputable vender. And weather or not it needs a gasket as well. Thanks in advance, Benny64
