The BOLT-68, a bullhead watch that converts into a pocket watch.

Bomberg Bolt-68

Bomberg is a  fairly new watch brand, being established  in 2012 in Neuchâtel, the heart of Swiss watchmaking.

For 2014 they introduced the BOLT-68 collection. Its an interesting and unconventional watch in the mold of the ‘Bullhead’ design which originally started appearing in the 60’s but is still being used even by major brands, Omega having recently released an updated version of their model, the Omega Seamaster Bullhead, which you can read about along with other Bullhead designs here.

An additional, unusual feature is that the Bolt-68 watch-case can swivel and slide back, so that it can either be used as a pocket watch by attaching a chain -along the lines of what Bovet has been doing-  or used as a wristwatch.

Bomberg describes it like this: “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. The new configuration is now a pocket watch. But be warned, the chain differs quite a bit from the fine chains on the pocket watches of yesteryear. The links are robust, imposing, oversized like the watch, with the two snap hooks clearly visible from end to end.”

The Bomberg Bolt-68 Chronograph collection is made up of quartz and automatic equipped timepieces, they use Swiss Ronda movements, the quartz models are 45mm in size, and the automatic models use a Concepto caliber 99001 and are 47mm. They have stainless steel and PVD treated steel cases which are water resistant to 10 ATM. A reinforced K1 mineral crystal with sapphire coatings are used on on all Bolt-68 timepieces, with a single non-reflective coating.


The Bolt-68 comes in quite a few variants some of which are shown below, for more information visit Bomberg.

Prices range from $795 to $3995
