An exceptional example from Zenith's Sporto collection of the 1960s, this vintage timepiece showcases the brand's commitment to precision engineering and refined aesthetics.
The case is crafted from 18k yellow gold and features a substantial 35mm diameter, exemplifying the preferred proportions during this golden era of watchmaking. The case back, notably unsigned by Zenith, reflects certain production variants characteristic of mid-century manufacturing practices.
The dial configuration presents a seconds sub-dial positioned at 6 o'clock, while the plexiglass crystal, a hallmark of vintage horology, lends an authentic period character.
The watch is powered by a manual-winding mechanical movement, ensuring the tactile engagement and reliability that discerning collectors value.

The original two-tone brown leather strap, measuring 23 centimeters, is complemented by a gold-plated buckle that has acquired an elegant patina. With a gross weight of approximately 35 grams, this Sporto remains in excellent working order, with all complications functioning as expected.

A remarkable acquisition for those seeking an authentic example of Swiss watchmaking heritage.
