watches 45MM


This Swiss wristwatch has a black dial with bold red accents on the sweep hand and chronograph dials, a black strap with bright red stitching. A beautifully balanced look of subtle red splashed on black, with fine precision technology inside. A solid timepiece, both rugged and elegant, that will always be there when you need it. Like you, this watch can straddle multiple worlds – relaxation, work deadlines, nights on the town, adventure travel, all of it. And like all BOMBERG BOLT-68 chronographs, this wristwatch transforms into a disruptively cool pocket watch with our patented “bayonet” system and the included medallion and chain. 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.
