This thread hits a home run with me as I am the proud owner of two vintage Moto Guzzi V 1000 and of an ultra modern Honda DN-01. In summer my life revolves around biking in the Jura Mountains.
Whenever I talk with my motorcycle buddies about watches they want the dial to be uncluttered and easy to read the time from. Quite a few of my chums wear a special beater when they take their bikes for a spin and many of them wear the watch on a Nato-strap which is long enough for the watch to be worn over the sleeve of the jacket. We are all riding vintage bikes without any clocks in the instrument section of the bike.
I personally do not wear my watch on the outside of the jacket, however as more ofthen then not I do wear watches adorned with diamonds or other gem stones.
Most brands of bikes have a watch or two in their accessories collection. But as Dennis outlined most of the watches do not take the bike-theme further than the name of the brand on the dial.
In 2003, I proposed a special watch to Moto Guzzi. We had the case PVD-plated in exactly the same hue of red the old Moto Guzzis sported and the dial had a kind of inlay in the shape of the tank of a California of the 1st series viewed from out the rider’s perpective when sitting on the bike. They bought the design but the watch was never manufactured as they estimated the market to be too small.
From what I have learned only Harley-Davidson commands enough of a following outside the bikers’ realms warranting a special series of watches. Probably that is why we do not have too many brands of bikes seriously contemplating a watch collection which takes the theme beyond the mere sticking of the brand’s name on the dial, on the clasp, etc.
