watches 45MM


Pure gray – the dial, casing, crown, plush strap and stitching, even the numbers and accents are a play of light and dark gray. This precision Swiss wristwatch is sophisticated, cultured, a citizen of the world, at home anywhere, agile, supple, conversational but not talkative. If you are drawn to this solid and elegant piece of fine technology and self-assured attitude, it is because it reflects your own evolved and accomplished self. Like all BOMBERG BOLT-68 watches, this comes with a beautiful sandblasted gray chain and medallion to convert the wristwatch into an ultra-stylish pocket watch, via our patented bayonet system. Movement, design, and assembly all made in Switzerland.

After 1968, BOMBERG introduced its second product line collection in 2014: the BOLT-68. The collection's name itself carries the entire brand DNA: "68" in reference to one of the most significant years of the 20th Century, and "bolt" to emphasize the collection's strength and designed impact.

The most unique and disruptive aspect of the BOLT-68 is its transformative ability. Using an ingenious bayonet system with a trigger guard – an exclusive system patented by BOMBERG – the time-keeping module can be detached from its base and attached to a metal chain to be transformed into a masculine pocket watch. The chain differs quite a bit from the fine chains on the pocket watches of yesteryear. As you will no doubt have realized, this tool is destined more for a pocket on a pair of jeans than that of a gentleman's waistcoat. All BOLT-68 collections include the chain and medallion for turning your exclusive timepiece into a disruptive pocket watch.

Two versions of the BOLT-68 are available: The Bolt-68 Chronograph quartz models measuring 45 mm in diameter and powered by a Ronda caliber 3540D quartz movement, and The BOLT-68 automatic models measuring 47 mm and powered by a Concepto caliber 99001 automatic mechanical movement. The BOLT-68 collection is available in a variety of stainless steel and PVD treated steel cases. The top-of-the-range model, the BOLT-68 Skull, has been produced as a limited edition with a black metallic chain whose links represent a series of skull and crossbones.
