It’s ticking!

Filed under: Exciting @ 7:16 pm

Almost a month after I ordered all the pieces, the alpha version of my new watch is ready and ticking!

The last part arrived about 10 days ago and it took about 5 hours to get it all together. Unfortunately, the bezel came with a small dent and a new one is on the way. The hour hand has a bit of metal showing and another one is en route as well.

After the initial casing and regulating in the dial up position for 48 hours, I decided to do a final cleaning of the case and install the winding rotor. Since I’m a moron, I dropped the movement onto the case when installing it for the final time! :wallbash: The freaking dial got scratched and a new one is on order.

Anyways, after another week of regulating, I wore it for the first time today. So far, the movement runs really well and is +3.5 to +7 seconds per day depending on the position. We’ll see how it runs with wear.

Nice. You’re gonna have to teach me this stuff one day. I’ve been researching watches like crazy again these days.

Jack, I am really impressed. My dad was a watchmaker, and I spent my entire childhood at his shop watching him disassemble and reassemble watches for his customers (only good ones he thought were worth his effort). Unfortunately, he never passed any of his knowledge or skills onto his son, so he had to become a doctor instead.

Jack, that watch is looking great! Especially love the fat hands. And a quality Seagull movement inside too – I’ve been looking for one of those for ages. Feel free to email me wih tips on suppliers! Good luck with all your projects.
