This Nivada Grenchen Chronoking Aviator Sea Diver, reference 87033M04, is offered brand new and unworn, with its original Nivada Grenchen box and papers, and is covered by the brand's manufacturer warranty from the date of purchase. Nivada Grenchen rebuilt its 1960s Chronoking from the original drawings: a 38 mm stainless steel case with a black rotating bezel, pump pushers and a double-domed sapphire crystal. The dark blue dial carries two tan counters, Super-LumiNova hour markers and hands, a red central chronograph hand, the tachymeter and telemeter scales of the original, and the date in a window at 12 o'clock. The case is water resistant to 100 meters. Inside is the Swiss Sellita SW510 M hand-wound chronograph caliber, beating at 28,800 vibrations per hour with a 63-hour power reserve. The watch comes on its original stainless steel beads-of-rice bracelet, 20 mm at the lugs, closed by a hidden folding clasp. Having never been sold or worn, the watch has not required servicing. Scope of delivery: the watch, its original Nivada Grenchen 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 Nivada Grenchen Chronoking before purchase and usually reply within a few hours.
