Automatic chronograph project watch
Here's my automatic chronograph built from parts.
The case is made of treated titanium and the glass is sapphire. The case has a diameter of 41 mm and a height of 14 mm.
Inside is an ETA/Valjoux 7750 cam & lever style automatic chronograph movement. I opened the case today in order to apply some silicone grease to the crown and back gasket. It's been raining lately so I wanted to help make it a bit more waterproof and thought it was a good opportunity to take some pictures.
The back features a display caseback.
The movement runs good :) I plan to service the movement myself if it ever needs to be serviced (complete dissasembly, cleaning, oiling and re-assembly).
Total cost of parts in USD:
$390 - ETA/Valjou 7750 elabore. I bought mine from Ofrei, an American jeweller.
$220 - Case, dial and hands. I bought as a set from Duplain Horlogerie, a watch part supplier from Switzerland.
