Model: Sinn 356 Copper (SUG)
Overview:
A distinctive take on Sinn’s classic pilot chronograph, the 356 Copper SUG variant combines traditional tool-watch design with an unexpectedly refined guilloché dial.
History:
Produced in the 2000s, this earlier SUG-era Sinn 356 features the highly regarded Valjoux 7750, predating the later transition to Sellita-based calibers. These earlier examples are often preferred by collectors for their movement pedigree and period-correct execution.
