# Cartier Tank Must SolarBeat: Modern Practicality Meets Timeless Design

Cartier's decision to introduce solar technology into the iconic Tank collection represents a pragmatic evolution for a design that has remained virtually unchanged since 1917. The Tank Must SolarBeat WSTA0059 preserves the collection's defining rectangular case and Art Deco proportions while addressing the legitimate demands of contemporary watch ownership. The 33.7mm stainless steel case feels appropriately proportioned for modern wrists, and the green dial—a subtle departure from traditional black or silver—provides enough personality to distinguish it without compromising the watch's essential elegance. The Cartier SolarBeat caliber, operating at 32,768 vph, ensures a smooth sweep second hand while eliminating the mechanical vulnerability of traditional automatic movements. With a thickness of just 6.6mm, the watch slides comfortably under a dress shirt cuff, making it genuinely wearable rather than merely aspirational.

The target owner is a professional who values heritage and restraint over novelty. This is a watch for someone attending board meetings and formal dinners with equal frequency, someone who appreciates that a Tank needs no complications beyond the time itself. The leather strap and modest 30-meter water resistance reinforce its positioning as a dress watch rather than a versatile tool.

At roughly $2,700 on the secondary market, the SolarBeat occupies an interesting position. It undercuts the perpetual-rotor complexity found in comparable Omega De Ville models while commanding a Cartier premium that many consider justified. For those seeking solar convenience without sacrificing genuine design pedigree, this Tank delivers more substance than most competitors in its segment.
