Christopher Ward Calibre CW-003

Christopher Ward · Hand-wound · Premium tier · Family: Christopher Ward CW-003

Hand-wound in-house movement made for The C12 Loco (2025) and, per the brand, unique to that watch: 138 components, twin mainspring barrels for a 144-hour (six-day) power reserve, and an inverted free-sprung balance with a 0.045mm hairspring and regulating screws, shown on the dial side at 6 o'clock; the escapement and balance were developed with Feller Pivotages SA. 4 Hz, 29 jewels; brand timing tolerance -0/+7 s/day (an internal benchmark, not COSC, per SJX). SJX traces its roots to the SH21. Functions are inferred from product photos, which show only hour and minute hands on the off-centre time dial (no seconds hand, no date), so hacking is not recorded. Diameter and height not published.
