I recently serviced this beautiful 1930's Hamilton Seckron calibre 980a doctors vintage watch for a regular ClockSavant customer. He has fantastic taste in interesting and unique vintage watches. I posted in March on his Vulcain Campos, another beautiful and very unique vintage watch. This watch features a unique dial layout designed to appeal to doctors and other professionals of the era wishing for focus on elapsed time with a larger seconds hand (aka measuring pulse for example) and the ability to quickly and easily read time. The watch is a great example of how Hamilton applied their outstanding quality and knowledge in pocket watches to the growing wristwatch market. Highlights include the shaped movement, beautiful curved case, innovative method of "moving" the hour and minute as shown on the dial side, an interesting mainspring click with an integrated spring (not easy to see in pictures), and astonishing accuracy for the era-- within about 9 seconds a day of accuracy averaged across all positions. As shown, the dial has its own metal backing plate. The case splits in the middle and requires patience and skill in extracting the movement-- if you are prone to put your screwdriver into places that look like "slots," you will destroy the time train of the watch. This is one of the few watches coming across my bench that was treated well by past watchmakers. It was well cared for and appreciated by its past owners. Spend time with a watch like this and the marketing and brilliance of the Hamilton designers takes hold, the watch will draw-you-in and captivate you as it did for buyers and owners when it was new.
