About this entry

68% of key specs known. Missing: hardening, lume, bracelet links, end links, link attachment, clasp micro-adjust.

Surf-inspired round diver. Brand spec sheets: 316L steel, 41mm, 47mm lug-to-lug, 12.25mm, 20mm lugs, rotating ceramic bezel, screw-down crown, "Franco-Swiss" G100 (La Joux-Perret, 68h), personalised date wheel, steel hands, domed sapphire with anti-reflective coating, green-tinted skeleton screw-down caseback, 100m; 84g on leather or 139g on the steel bracelet. Mars: green ceramic bezel; its sheet leaves the case material out ("Boitier rond en de 41 mm") and gives 63g, but it is sold at the steel prices and its photos show the steel case and bracelet, so it is recorded here. Prices are the French store's EUR prices as shown on the product pages, and they include VAT: the store's conditions générales de vente say prices are "toutes taxes comprises" at the VAT rate of the customer's country, and non-EU customers see ex-VAT prices only when logged in (the product pages add "Expédition et taxes calculées à la caisse"). Strap and bracelet options are recorded as prices with a configuration.
