About this entry

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

Quartz version of the Bonzer. Brand spec sheets: 316L steel, 41mm, 47mm lug-to-lug, 12.25mm, 20mm lugs, rotating aluminium bezel, screw-down crown, Ronda 517, steel hands, domed K1 mineral crystal with anti-reflective coating, screw-down caseback, 100m; 73g on leather or 127g on the steel bracelet. The sheets list "hours, minutes, seconds, date", but the photos show day and date, as the Ronda 517 has. 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.
