Mid-1930s IWC (International Watch Company) featuring the renowned Cal. 83 — a highly sought-after screw-back Calatrava with a rare applied sector Breguet dial.
This exceptional piece showcases a beautifully styled applied sector Breguet dial, a design also seen in Omega and Longines watches from the same era, capturing the distinctive aesthetic of the time.
The 30mm Calatrava case, with its early waterproof construction, exudes a solid, weighty presence. Though modest in size, the watch has a striking visual impact thanks to the tightly composed sector dial, giving it a presence that exceeds its dimensions.
Inside is the celebrated Cal. 83, one of IWC's signature small seconds movements.
