Very similar in design to models manufactured by Omega, it is safe to say that early Tissot chronogaphs are extremely rare. Housed in a very large case for the time (in the forties), this particular model has been preserved in exceptional condition. A very tight snap on caseback, a near perfect dial featuring both a telemeter and tachometer scale as well as beautiful flexible lugs that enhance its overall size on the wrist, a true time capsule.
