The present reference 7753SN (for Standard Noir) displays the so-called second execution dial and hands. These hands are fitted with a black insert to match the hour markers' design and longer luminous insert. Seldom found with two registers, the silver dial with black register is more often seen on three register watches such as reference 2447SN.

Launched in 1969, the present lot bears the serial number 105'378 which places it into the early 1970s production. It is interesting to note that reference 7753SN is the only non-military Carrera powered by a Valjoux caliber 7730 (Heuer used the Valjoux caliber 7733 in military issued reference 7753SN timepieces). The use of this caliber results in the case being thicker than its three register siblings.

With its no frills dial with almost Bauhaus zen feel, this timepiece, contrary to the majority of Heuers that bring to mind the smell of burnt rubber, gasoline and speed, has a somewhat elegant nonchalance. Fitted with a Gay Frères double grain bracelet stamped 4th quarter of 1971 this watch is in very good condition which, along with its ultimate rarity, will please the discerning collector.
