+1 - integrated bracelet might be in vogue now but costs you inflexibility further down the line.
Cosmic 2000s are nice watches but not massively appreciated as they usually have the last generation of Omega-made movements before the Quartz crisis bit deep. Also, some watchmakers don’t like working on them.
That said, I like the vibe of Cosmic 2000s and they have good wrist presence vs earlier vintage Seamasters. It all comes down to price!
