Zenith Respirator JFK Square Automatic

DESCRIPTION & SIGNIFICANCE

Introduced in the 1960s, the Zenith Respirator utilizes a highly advanced, multi-piece compression case designed to maximize water resistance through atmospheric and depth pressure changes. This specific 1962 reference is famously nicknamed the "JFK" or "John F. Kennedy" model due to its striking resemblance to the square-cased timepieces favored by the President. Highly sought after by collectors, this rare variant distinguishes itself by being housed in a solid 18k yellow gold case rather than the far more common gold-plated versions with a premier in-house 26 jewel automatic movement from Zenith's golden era.

It is estimated total production of this timepiece is likely in the low hundreds
