About this entry
87% of key specs known. Missing: weight, hardening.
Quartz chronograph from the brand's early years (the Chrono S store page dates from November 2013; Worn & Wound reviewed the line in June 2014). Brand specs, the same on all three listings: 44mm, 316L with a signed screw-down crown, sapphire with AR on both sides, Ronda 5050.B, 100m, 20mm lugs. The S is the same watch in black PVD; the Bleu has a blue dial and a brushed steel bezel with C1 Super-LumiNova on the 60-15 minute section. Worn & Wound measured 50.9mm lug-to-lug and 12.6mm thick (not said whether over the crystal; recorded as total), and describes a unidirectional 120-click bezel, lumed baton markers and sword hands, a big date at 6 and prices from $550 to $595 depending on strap and finish in 2014. The store pages show $575 (Chrono) and $595 (S and Bleu) but are sold out and sit in the brand's Archives collection.
