[Timestamp first & pics with timegrapher photos](https://imgur.com/a/4aWAvXe) A beautiful c. 1940 Hamilton 917 10s pocket watch movement converted into a cool black dialed pilot watch with the sub-seconds at 9 o'clock. Fully disassembled, cleaned, reassembled, lubricated, and then poised to 6 positions (all 6 positions maximum variation is about 25 seconds, from the factory 3 positions were required to be within 30 seconds). I would recommend winding every 24 hours, as after the amplitude starts to fall off the timing suffers. Based on my test it has a power reserve of around 38-40 hours, but still, I'd wind it every 24 hours. It has an alloy mainspring which is less likely to snap. Should be a great time keeper. The balance isn't shock protected on this movement - so no hammering or golfing with this one - it's a dress watch. Should be life waterproof (rain, hand washing, sweat, etc.) The case is rated to 3 ATM but I can't test it. The back has an o-ring as does the crown. I wouldn't suggest swimming or showering in it. Stainless steel case. Sapphire front glass, back is mineral glass for viewing the pre-WWII American made movement. These are super pretty considering they were put behind a solid back in the pocket watch to be seen only by the watchmaker. The sapphire doesn't have an AR coating on it that I'm aware of and you can see my camera reflection in some pictures. The metal dial is black, and it has an inner hour chapter ring that has yellow numbers. The hands/dial are luminous. New leather strap with buffalo grain, but you can put any 22mm strap you like on it. Case is ~44.1mm, 49.xmm including the crown, and 51.x mm lug to lug. A good healthy sized piece of American history. Tons of pictures including all 6 positions on the timegrapher. The amplitude is very close to correct as I used 46 degrees as the lift angle. It's not published, but it's pretty close by observing the balance in slow motion. Price $450, OBRO, in the USA including shipping. Payment by PayPal by friends and family. If you have good references and want to pay the +3% I can accept goods and services. International shipping possible by you can figure around +$40 depending on your location because of insurance and having to ship priority mail to even be able to insure it. Not really looking for trades. However, if you have something I could service and sell at a profit I would consider it. Or an Omega Aqua Terra Skyfall - either size LOL :)
