Bremont is a brand known for their aviation and military associations and the extreme conditions their mechanical movements are able to withstand.

Like limited edition watches before this Bremont also is a tribute to famous military history using actual material sourced from historical items related to the concept. For example the previous limited edition model the Victory used original parts of the HMS Victory.

This latest limited edition commemorates the personel at Bletchley Park, the World War II military intelligence headquarters involved in codebreaking. Bletchley Park was the site of the United Kingdom’s main decryption establishment during the Second World War and they significantly helped to hasten the end of the war by unlocking the secrets of the German Enigma and Lorenz machines.

Some of the proceeds from the sales of the Bremont Codebreaker watch will be donated to the continued restoration and preservation of Bletchley Park.

Bremont Codebreaker – Case and Dial

Like most Bremont watches the Codebreaker measures 43 mm in diameter, it comes in either hardened steel or rose gold. Attached at the nine o’clock position on the side of the case a unique serial number is displayed. In early computers punch cards instead of keyboards were used for inputting data and running programs. Bremont acquired five of these cards and the numbers from them to indicate the edition number of the watch thereby including a piece of code breaking history from World War II.

The codebreaker is a limited edition of 240 units in steel and 50 in rose gold. The crown of the Bremont Codebreaker watch also incorporates material from components salvaged from Bletchley Park, in this case using wood from a building called Hut 6. Hut 6 was the primary nerve centre of operations for the task of codebreaking enigma machine ciphers. Its wood from the floorboards of this hut that was used and inlaid into the Codebreaker’s crown.

Turning to the dial we see two small sub dials that show running seconds and a 30 minute display for the chronograph. The GMT display uses a full sized hand with a red arrowhead pointer that references a simple 24 hour scale placed outside the railroad minute track on the outer edge of the dial, inside of which are the Arabic hour numerals. There is a date display at six .

Bremont Codebreaker – Movement

The Bremont Codebreaker is powered by Bremont calibre BE-83AR which has 39 jewels and a power reserve of 46 hours . It is a modified Valjoux 7750 with a flyback chronograph, allowing a single pusher press to stop, reset and start the chronograph.

Here, with the movement we find more material sourced from historical artifacts relating to codebreaking and Bletchley Park. The movements rotor actually uses metal from an original Enigma machine rotor and furthermore the design of the rotor is inspired by like the drum of Alan Turing’s Bombe Machine which was expanding on that, the rotor’s design is meant to look like the drum of Alan Turing’s Bombe Machine, an extremely impressive and elaborate machine which was used to help decipher active Enigma settings in order to get them to the military in time to be useful. The rotor also aptly has a coded message on it.
