Super quality


So happy you can order parts!

I crashed with my bike and damaged the case of my Alpha Daytona. Ordered a new case the next day, got it a few days later, transferred over the movement and the watch is like new again! Great service from Alpha!

Looks and feels very good.

Put my st1903 from my alpha 1965 in this case today, it looks beautiful and the renewed casing makes it get wrist time again.
