Adding to the line of timepieces equipped with a dead-beat seconds mechanism, Arnold & Son will present the CTB at Baselworld 2014, which combines both a chronograph and a dead seconds.

At Baselworld 2014 Arnold & Son will officially unveil Chronograph True-Beat (CTB), the world’s first chronograph combined with a dead seconds mechanism. Both the elapsed seconds hand of the chronograph and the dead-beat seconds are co-axial in the centre of the dial. The dead-seconds runs continuously, functioning as the constant seconds, while the chronograph can be started on demand. The sub-dial at six is the 60 minute counter, while the time is displayed in the sub-dial at 12 o’clock, set against a grained grey dial.

Automatic with a 50 hour power reserve, the A&S7103 movement was developed by movement specialist La Joux-Perret, the sister company of Arnold & Son. This is yet another calibre equipped with a dead seconds mechanism, which has practically become a hallmark of the brand. Also to be launched at Baselworld is the DSTB, which has an exposed dead seconds mechanism on the dial.

The case is steel and measures 44 mm in diameter. The CTB will carry a retail price of 23,800 Swiss francs, which is equivalent to US$27,000.
