DIY Beadblasting on my “new” Sinn 256

Just wanted to share a fun DIY project I just completed. I recently purchased a roughly 20 year old Sinn 256 from Japan. The watch was well cared for but the matte beadblasted finish was getting a bit shiny on the lugs and sides of the case. The bracel…

Sinn to Present at 2026 Watches and Wonders

Hodinkee reports that Sinn, amongst 9 other brands, will join the fair in 26. My initial thought is they must have something significant to share in the works, as it’s a considerable expense to participate. New model? Refreshed cases on mainstays ( t…
