Bought these and others from one second closer a couple of years ago. kept the ones I used and these have not been used (they have been tested several times, but never used) The Bezel fits all Vostok Amphibia classic cases and includes the tension spring. If I remember correctly the bezel is the Atlas one Matte Black IP Coated SS bezel. The bezel inserts fit the bezel and also fits all Seiko SKX 007/009 bezels. All bezel inserts are aluminum. Selling all for $55 including shipping. I accept PayPal or Venmo (please include fees) ,shipping to CONUS only with tracking and Insurance included. I am selling the whole set and not separate pieces as it would not be worth my time to sell individual parts. The set is heavily discounted.
