This Charriol Mariner 20 mm in steel with the black dial, reference MA20S.520.002, is offered brand new and unworn, with its original Charriol box and papers, and is covered by the brand's manufacturer warranty from the date of purchase. The Mariner takes its case from a link of a ship's anchor chain: a 20 mm rectangular case in polished stainless steel, framed top and bottom by twisted-cable bars and by the curved links of the chain at each end, under a sapphire crystal. The black dial carries a diamond at 3 and at 9 o'clock, blued hands, the Charriol Genève signature and the house monogram. The case is water resistant to 30 meters. Inside is a Swiss quartz movement showing hours and minutes. The watch comes on Charriol's bracelet of five slender steel cables with steel end pieces, made in La Chaux-de-Fonds, closed by a folding clasp. Having never been sold or worn, the watch has not required servicing. Scope of delivery: the watch, its original Charriol presentation box and papers, a full set. Ships from Houston, Texas within 1 to 2 business days by DHL or FedEx, fully insured. We are glad to send further photographs or a live video of this Charriol Mariner before purchase and usually reply within a few hours.
