Description from the seller
Arcaido: time sculpted in bronze. The Italian experience, since 1993, meets Swiss Made craftsmanship and a living material that develops a unique, unrepeatable patina as individual as the wearer.\n\nIn this auction we offer: Arcaido - Primo GMT Bronze - Swiss Made - Sellita SW330 Special Élaboré - Diver 300M - 42.5 mm - Deep Sea Bronze CuSn6 - Sapphire & Ceramic Bezel\n\n42.5 mm Swiss Made GMT diver watch in solid marine bronze CuSn6, unidirectional bezel with 120 clicks and a matte black ceramic insert, anti-reflective sapphire crystal, exhibition case back, decorated Swiss automatic movement with a second time zone, 30 ATM/300 m water resistance, Made in Italy leather strap. Luxury box with a second NBR rubber strap and a tool kit for interchanging. Brand new with documents and official 2-year warranty.\n\nPrimo GMT Bronze is a diver built with a material that very few actually use: solid marine bronze CuSn6, the alloy employed in naval environments to withstand seawater. Not a coating, not a surface treatment applied to steel: the case, bezel and crown are bronze through and through, from the exterior to the core.\n\nThis is what makes every specimen different from all the others. Bronze reacts to air, to skin, to salt spray, and over time develops a patina that no other watch will have: it darkens in the engravings, lightens where the sleeve friction polishes it. Who buys an Arcaido does not buy a finished object, but an object that keeps on working.\n\nThe GMT function allows reading a second time zone thanks to a fourth central hand, paired with the 24-hour scale printed on the dial: home time remains on the main hands, the second time zone is read on the 24-hour scale, with quick time zone and date adjustment. A tool designed for travelers who want to keep two times in view.\n\nThe construction is that of a true instrument. 300 meters of water resistance, unidirectional 120-click bezel with matte black ceramic insert — raised numbers and scale, a material that resists scratching and staining — sapphire glass with anti-reflective treatment, black dial with applied indices and Swiss Super-LumiNova BWG9, white in daylight and blue in the dark.\n\nThe exhibition case back in 316L steel with sapphire lets you observe the Swiss automatic movement at work: circular graining, blued screws and a customized IP black rotor that spins with every wrist movement. It’s a finish usually not found in this price range, and here it is not hidden under a closed case back.\n\nThe strap is Made in Italy leather, hand-stitched and interchangeable thanks to two removable end-links. In the luxury box you’ll find the second strap in NBR rubber and the complete tool kit: the bronze buckle is one piece and moves from one strap to the other with the kit provided. The case and buckle are in the same bronze and develop the same patina together. Leather for everyday wear, rubber for the water.\n\nDIAMETER: 42.5 mm\nTHICKNESS: 13.5 mm\nLUG WIDTH: 20 mm\nCASE: solid marine bronze CuSn6, polished and brushed finishes, two removable end-links\nWATER RESISTANCE: 30 ATM (300 m / 1000 ft)\nMOVEMENT: Sellita SW330 automatic Swiss Made, Special Élaboré — 25 jewels, 42 hours power reserve, circular graining, blued screws, customized IP black rotor\nFUNCTIONS: hours, minutes, seconds, date, GMT second time zone with 24-hour scale on the dial\nGLASS: sapphire with anti-reflective coating\nBEZEL: solid marine bronze CuSn6, 120 clicks, unidirectional, black matte ceramic insert with raised numerals and scale\nCASE BACK: screw-down in 316L steel with sapphire and original Arcaido pattern, movement visible\nCROWN: screw-down in CuSn6 bronze with ceramic insert\nDIAL: DeepBlue, applied indices, Swiss Super-LumiNova BWG9\nHANDS: Swiss Super-LumiNova BWG9\nSTRAP: Made in Italy leather, handmade, interchangeable\nBUCKLE: bronze ardiglione (pin buckle) in CuSn6\nLUXURY PACKAGE: watch, second strap in NBR rubber, tool kit for interchangeability with two tool holders, user manual\n\nNOTE ON PATINA: bronze is a living material; the tone of the case may vary slightly from the photos and will naturally evolve over time. It is the signature of every Arcaido: no two pieces are alike.\n\nCUSTOMIZATIONS: the auction lots do not include Atelier customizations.\n\nNew, never worn. Complete luxury box, documents and official 2-year warranty. Returns accepted only if protective films have not been removed and the watch and its box are in the same condition as when shipped. Swiss Made.

Hard work, innovation and passion for new ideas, thanks in part to the dedication our founder’s son, we continue to push the possibilities for our company.
