I'm looking for a Speedmaster for a girl friend of mine, but the Professional is too big for her. Hesalite and a similar dial are a must. Omega says the 3150.50 is a 35.5mm size, but a lot of the one's I see for sale claim to be 39mm. Can anyone clear this up for me? Is there a smaller Speedmaster with Hesalite?
35.5mm without the bezel, 39mm with the bezel. If you are locked in to a speedmaster with hesalite < 42mm, reduced is about it I think.
