This Seagull 1963 watch is a reissued version of the Chinese Air force Mechanical Chronograph, a unique and classic masterpiece now searched for by collectors nearly as much as the original. Both available with a sapphire glass on the front and an exhibition (open) case back. The sapphire glass version of the Seagull 1963 chronograph is a popular choice by many due to its higher durability and strength.
The movement is a Seagull st19 mechanical (hand winding) chronograph with 21,600 bph. The power reserve of the Seagull movement is about 42 hours on a full wind without the chronograph running.
