Vintage Omega Seamaster Chronostop Ref. 145.007 Stainless Steel 1170 Bracelet

Omega first introduced this Chronostop model in 1967. Measuring 41mm across the case, this is one of the largest vintage models by Omega.  The chronograph mechanism is similar to a 'fly-back', the orange chronograph seconds hand can be started via the pusher to the case side, pressing the same pusher again will automatically stop and reset the second hand to the 12 o'clock position. This means that the orange hand can be used either as a constant seconds hand or to time intervals up to a minute in duration. The inner bezel is calibrated for tachymeter which allows the user to measure the speed of a travelling object over a fixed distance.
