Bremont Z Series - ALT1-ZT/51

The ALT1-Z formed part of the launch collection back in 2007, and has become central to the Bremont offering over the years. Basel 2015 saw the launch of an updated version with the highly anticipated ALT1-ZT. This range was designed with aviators and world travellers in mind. Legibility was absolutely essential when it came to the aesthetic.

The ‘ZT’ stands for ‘Zulu Time’ and allows the wearer to display local time together with the official world time standard. Unsurprisingly the Z chronometer has proven to be widely popular amongst the military squadrons Bremont works with - a significant and ever-increasing part of the Bremont business. The ALT1-ZT/51 adds a new dimension to the range whilst integrating a very important design cue from Bremont’s past.
The ALT1-ZT/51 maintains the clean legible dial with its new applied and bespoke coloured Super-LumiNova® index markers, and with the 24hr function having been moved to the bezel for improved clarity. Greater detailing around the stepped sub dials with micro lines on the ZT models has been made to give the dial more depth.
Functionally the ALT1-ZT/51 has the same features as the ALT1-ZT/BK with the integration of the Roto-Click® bi-directional inner rotating bezel. The GMT hand combined with chronograph functionality measuring seconds, minutes and hours make this model ideal for travel.
For additional clarity Bremont deploys the same hand design as the MB series, including the second time zone marker, which has been so effective on the MBIII. The ALT1-ZT/BK hands are used again but this time with several layers of bespoke coloured Super-LumiNova®.
As with most core range pieces the ALT1-ZT/51 has a specially treated 43mm stainless steel case made to an exceptional hardness of 2000 Vickers, which is seven times that of an average stainless steel watch case.
The convex sapphire crystal is equally as hard and has nine layers of anti-reflective coating applied to both sides of the glass for increased legibility. The high standard of finish and attention to detail seen in everything from the hand-cut and engraved winding rotor in the sapphire crystal case back to the meticulous machining of the three-part Trip-Tick® cases take considerable time and skill to apply.
