Something a bit offbeat today... a 1950's Rolex 6106, a semi-bubble back with a 35mm case and the Super Oyster crown. This one is a radium dial, in original untouched condition, with the red "Officially" (as in Officially Certified Chronometer). I was lucky enough to buy this from a gentleman who specializes in fixing bubble-backs, and got it freshly serviced. The movement is in top-notch condition, and worked perfectly today even though I haven't worn it in months. I didn't even wind it, and it has barely lost 2 seconds in the past 10 hours.
