Universal Geneve Cal. 283 vs 285: Hand & Dial Specs

berrychlossom · Mar 24, 2026

Hi,

I'm working on a compur chronograph project and I'm running into some issues sourcing parts. I was wondering if someone familiar with 285 and 283 movements can verify if the hands and dials of these tow calibers are interchangeable.

Thanks

Diameters and hand sizes are different. Cal. 283 has 1.60 and 0.98 mm hand sizes, Cal. 285 1.80 and 1.16 mm
