757 III

The 756 and 757 series feature a striking design, contrasting displays and clear readability.

We have developed a special, new colour scheme for the 756 III and 757 III editions, which are limited to each 75 units. High-contrast, matt colours with a glossy, fine-satinised, stainless-steel case and sapphire crystal. The white hour indices and the 3, 6, 9 and 12 hour counters against the dark-blue dial ensure optimal readability. The chronograph hands and minutes stand out in orange, while warm-grey counters accentuate the striking face of these duochronographs.

The range of technologies in the watches includes Magnetic Field Protection up to 80,000 A/m, Ar-Dehumidifying Technology for increased functional reliability and freedom from fogging, Temperature Resistance Technology for reliable function in temperatures of –45°C to +80°C, and a highly scratchproof case based on TEGIMENT Technology. The watches are also resistant to low pressure and pressure-resistant to 20 bar.
