Pinion
A rare one-person connection from design sketch to final regulation, with unusually clear disclosure of Swiss and German component origins.
Verification note
Official pages clearly identify founder Piers Berry as designer, assembler, regulator and tester, while naming Switzerland and Germany as principal component sources.
The record
Piers Berry both designs and physically builds Pinion’s watches in England.
Cases, dials and movements are sourced primarily from Switzerland and Germany. Final assembly, case finishing, engraving, regulation and testing happen in England.
Pinion publishes a practical timing method: each movement is adjusted and tested in three positions, with a stated target around ±5 seconds per day before final acceptance ranges are applied by model.
Editorial angle
Perhaps the cleanest Tier II provenance statement in the sector.
