Size - 6mm x 5mm
Fit stem 0.9mm
Great case! Perfect for my diy project. I am using a Valjoux 7330 movement inside it. Did some few alterations with the pushers since it came longer and also had to get an adaptor for the stem and crown. Still in progress. Looks between a breitling top time and a heuer 60s Carrera. I’m really satisfied. Thx a lot.
