While I'd love to own a Seamaster 300LE, I doubt I'd be able to get one at a decent price down the line (unfortunately, funds don't allow for one at this time, or in the near future).
But I've recently been taken by the 300MC with Sedna or yellow gold. And I think I'd actually prefer these models on the strap rather than the bracelet (I've totally come round to two-tone watch heads, but not to TT bracelets - not yet anyway!). The one I really want is the blue dial/bezel, Ti head with Sedna (18.104.22.168.03.001):
Many are aghast at the idea of these dressy divers ("A dive watch with gold? On Barenia?!"), but I think one of these models would complement the other watches in my collection quite nicely...
No definite plans to track one down, but if one presented itself at a big enough discount, then who knows?
