i like it for more than just the fact that its 1964 ish. i've always liked Breitlings, owned several, but dont own any at the moment. they are superb looking tools, especially the earlier pieces. the slide rule bezel is very clever despite the fact that i've never managed to work out anything other than MPH/KPH comversion
the movements are always good and you cant really go wrong if you buy one. i'm not such a fan of the V7750 chronomats. my favourite 'modern' Navi is the Montbrilliant Spatiographe. why oh why did i sell it, it was unique before Porsche produced the Indicator.
these both deserve to be worn though. they must be very sad living in a dark box in the bank
