Movado Tri-Calendar

Movado Tri-Calendar Ref. 4820 | 18k Rose Gold | Turtle Lugs | 1950s

Description

This rare vintage Movado Tri-Calendar Ref. 4820 comes from a time when Movado was producing some of the most refined complicated watches in Switzerland. Long before the Museum Dial era, this was a brand deeply respected for elegant engineering and thoughtful design.

The solid 18k rose gold case measures a well-balanced 34 mm and wears beautifully on the wrist. What truly sets this reference apart are the turtle lugs. Sculpted, curved, and full of personality, they give the watch a presence that immediately separates it from more conservative mid-century dress watches. These lugs are not just decorative, they’re a major reason this reference is so sought after today.

The tri-calendar layout delivers day, date, and month in a clean, symmetrical format that feels purposeful rather than busy. Everything is legible, well-spaced, and true to 1950s design sensibilities. Power comes from a hand-wound Swiss movement, which adds to the tactile charm of owning and using a proper vintage calendar watch.

This example is fitted with an aftermarket strap and buckle, a practical replacement that keeps the focus where it belongs, on the rare case, original dial, and complication.

Historical Significance

In the 1950s, Movado was producing calendar watches that rivaled far more famous names in both quality and design. The Tri-Calendar models represent the brand at its technical peak, combining practical complications with elegant case architecture. References like the 4820, especially in solid rose gold with distinctive turtle lugs, were produced in limited numbers and are rarely encountered today. For collectors, this watch offers genuine mid-century complication, sculptural design, and the warmth of rose gold in a single, cohesive piece.
