@Khamenman Good idea. I think it is down to the Damasko and one of the Sinns, not sure if I want to spring for the 856.
From the brand itself, I think Sinn has "bigger" name than the newer Damasko, but Damasko is using ETA while Sinn is using Sellita, and personally I prefer ETA compared to Sellita. On top of that, Damasko hardened case is better than Sinn's case. Another cherry on top of that, Damasko also has their own patented crown/gasket technology. I always welcome better technology. So yeah, IMO, I like Damasko better.
