Omega Chronostop Ref. 145.007

The History

The Omega Chronostop reference 145.007 is a part of the Omega Chronostop family of watches that launched in 1966 as part of the larger Seamaster collection. While there are multiple designs and iterations within the Chronostop family, there is one feature that binds them all together: the unique chronograph mechanism. Unlike most chronograph watches that feature multiple pushers, the chronostop has a solitary pusher that conveniently handles multiple tasks. 

Now, you might be asking yourself how useful this single pusher, 60-second stopwatch actually is in practice. The answer? Not much if we’re being honest, but that didn’t hinder the Chronostop from becoming the official timer at the ‘67 Pan-American Games in Winnipeg and the ‘68 Olympic in Mexico. Omega even produced a special Latin American edition of the Chronostop for that year’s Olympics. 

The combination of a classic legacy brand, quirky complication, and cushion shape make the Omega Chronostop a winner in our books. 

The Reference

This Omega Seamaster Chronostop reference 145.007 was produced in the late 60’s or early 70’s and closely follows in the Chronostop family tradition with a 60-second single pusher chronograph. The center chronograph – the seconds hand – can be started by pressing the pusher once and can be paused by holding it in place allowing the wearer to take a reading. Once released, the seconds hand completes its rotation and flies back to the 12 o’clock position.

The Case

The watch features a stainless steel cushion shaped case which appears to have been polished throughout. The crown is located at the four o’clock position and is signed with the Omega logo. Above that, at two o’clock, is the single chronograph pusher which is used to start, hold, and reset the chronograph function. The case measures 40.5mm in diameter, 47mm lug-to-lug, 22mm lug width and 14mm in thickness.

The six notch, screw-in case back is stamped with the Omega Hippocampus as well as the Omega symbol, the words Seamaster, and waterproof tested 120m. The acrylic crystal is in good condition with a few minor scratches.

The Dial and Hands

The center chronograph seconds hand, with its bright orange finish, is the crowning touch of this reverse pie-pan dial and shines on its perch at the top of the hand stack. The black dial features an outer Tachymetre that encloses an inner white chapter ring with increment markings down to ⅕ of a second. The black center dial has applied rectangular shaped indices for all hours except the 12 o’clock marker which sports a triangular shaped applied index. At the top of the dial, we see the Omega insignia with the Omega wordmark and Chronostop printed below it while at the bottom of the dial we see the classically styled Seamaster logo and T Swiss Made T surrounding the 6 o’clock index. The Omega logo is printed on the dial at top while the word Automatic – now faded – is printed at the bottom.

The Movement

The case houses a manually wound Omega-signed Lemania calibre 865 and is currently running and keeping good time with all functions of the chronograph working. The service history for the watch is unknown. 

The watch comes on an aftermarket black leather strap with an aftermarket buckle.
