Omega Seamaster Chronograph Calibre .321 Solid Gold Pulsations Dial

Ask any true watch collector about the greatest movements ever designed and there is a strong chance they will affectionately mention the Lemania Calibre .321 movement designed by Albert Piguet. Utilized in the original Omega Speedmaster during the American Space Program missions in the 1950s and 1960s, this workhorse movement has become a thing of legend, and deservedly so.

During the same time, Omega also made use of the Calibre .321 in another line of timepieces by installing it in their Seamaster Chronograph.  The Seamaster was a more stylish (and terrestrial) alternative to the Speedmaster, and the robust movement found its home in smaller and more elegantly designed cases offered in both steel and gold. 

This rare execution from the early 1960s boasts a stunning dial with both tachymeter AND pulsometric scales. The pulsometric scale was most often used by medical professionals to take an accurate reading of a patient's pulse - the chronograph is engaged as the pulse is read.  On the 30th pulse, the chronograph indicates the patients heart rate.  This function is often found on dedicated "Doctor's Chronographs" or has even been offered by other manufactures as an optional bezel insert for their standard timepieces, but is rarely found printed on a dial alongside a tachymeter scale.  Very cool indeed!

With a solid 18k gold case, beautifully patinated cream colored dial, recessed & textured subsidiary registers, teardrop indices and knockout dauphine hands, this lovely timepiece is thing of beauty any way you ‘treat’ it. (Pun intended.)
