watches 45MM


Here’s a classic, subtle, sophisticated, low-key beauty. The fine grey tint of the watch dial is echoed by the grey calfskin strap, for a unified and dignified look that suggests “speak softly but carry a big, fine timepiece.” Like all our BOLT-68 models, this is a solid, substantial watch, not a delicate, slender tidbit timer. Even the ridged perimeter of the watch face is an elegant touch. This wristwatch sounds a lot like you, doesn’t it? Wherever you sit, that is the head of the table. When you clear your throat, others fall silent to hear. This watch is perfect for all the events and activities of your complex, exciting lifestyle. When you need to time an event, this chronograph is there in all its precise Swiss glory. To cap it off, we include the medallion and chain that converts this stylish timepiece to an ultra-cool pocket watch via BOMBERG’S 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.
