I have for sale a brand new Omega Seamaster Stainless Steel Crown - Part No. 069ST43059 - which is still sealed in its original Omega packaging.

This crown fits, among others, the following case numbers - 145.0007, 145.0019, 145.007, 145.008, 145.013, 145.014, 145.020, 145013, 145014 and 146.011 - which includes the very rare Seamaster Bullhead and Soccer models as well as the Speedmaster Mark II. 

Original Omega parts like these are very hard to source these days so if you need one then grab this one while you can.

Please feel free to ask any questions.
