This silver dial retro watch is very collectable piece, very well made all stainless steel modular case, more precisely the case is not completely all stainless steel because the modular part in which the movement  is chrome is plated.  It is a part that is not exposed to damage when you wear watch and generally it preserves well  on many Spaceleaders,  but I think you should know it part is not stainless steel made.

Solid links all steel cuff bracelet perfectly fit to watch, with it watch looks beautiful, without that bracelet this watch is incomplete.

Glass is mineral crystal, movement is ETA Automatic cal. 2789 produced from 1969-1976, so this watch dated from first half of 70s.

Silver dial version is the most beautiful in my opinion, there are also blue dial versions, gold plated version and very rare orange dial version. This refers to the first generation of this model, later models were in other colors as well.

It looks very nice on the wrist and is very striking.
