Why Non‑Round Cases Matter

Non‑round watches push design boundaries while honoring mechanical craft. Cartier's Tank pioneered the rectangular aesthetic over a century ago; Franck Muller revived geometric flair with the Long Island and Conquistador. Today these shapes remain coveted for their wrist presence, architectural lines, and ability to turn everyday timekeeping into wearable art.

Cartier Tank: The Rectangular Original

Born in 1917 and inspired by military Renault tanks, the Cartier Tank set the standard for rectangular wristwatches. Variants span quartz and mechanical movements, steel to solid‑gold cases, and sizes from petite 20 mm to larger 35 mm profiles.

Franck Muller: Bold Geometry in Motion

Franck Muller re‑ignited interest in shaped cases during the 1990s. The Long Island line stretches numerals across a curved rectangle, while the tonneau‑shaped Conquistador delivers sporty presence in precious metal or steel.

Who Chooses Non‑Round Watches?

• Design minimalists drawn to clean lines
• Seasoned collectors seeking conversation‑starting silhouettes
• Style‑forward professionals who prefer wristwatches that break tradition

Our Collector Concierge

Every pre‑owned watch is rigorously authenticated and serviced, then protected by The 1916 Company's transferable two‑year global warranty. Our concierge team can arrange private viewings, global shipping, or sourcing of specific references on request.

Any timepiece whose case is primarily square, rectangular, tonneau, or other geometric form instead of a circle.
Yes—ergonomic lugs, curved case backs, and well‑proportioned dimensions ensure excellent wearability despite the unconventional shape.
Modern makers design in‑house or modified calibres to fit their unique cases, so accuracy and servicing remain on par with round counterparts.
Most use standard spring bars; some tonneau pieces require curved straps, which our concierge can source.
Every purchase includes a two‑year global warranty that covers authenticity and mechanical performance.
