Buran Flagman

The Buran Flagman collection offers Swiss made automatic mechanical chronograph watches in stainless steel, gold plated, solid gold and diamond set versions equipped with either ETA Swiss 7750 or ETA Swiss 7751 movements.

The movement beats inside the watch can be identified from the reference number, for example B50 indicates the ETA Swiss 7750 Chronograph caliber and B51 denotes ETA Swiss 7751 Chronograph movement.

Measuring 42mm or 43mm diameter, the watch case is water resistant to 30 meters. The watch features Sapphire crystal glass and alligator strap with deployment buckle.
