Big Date Automatic

BIG DATE Coin Edge Open Heart automatic

Delivery June 2026 - 1st drop of 50 pieces.

A refined expression of traditional watchmaking, the Prestex Big Date Automatic Open Heart combines classical design with contemporary mechanical detail. The beautifully textured dial features a prominent big date display at 12 o’clock, offering enhanced legibility while maintaining a clean, balanced aesthetic.

At 6 o’clock, the open-heart aperture reveals the beating movement within, adding depth and a sense of craftsmanship to the dial. Elegant blued hands contrast against the silver-toned guilloché-style surface, while applied Arabic numerals provide a timeless, highly readable layout.

The polished case is paired with a hand-finished leather strap, available in classic black or rich brown, delivering a versatile look suited to both formal and everyday wear. Subtle detailing across the bezel and dial reflects Prestex’s heritage approach to design, combining vintage inspiration with modern execution.

Powered by an automatic movement, the Big Date Open Heart is designed for those who appreciate mechanical watchmaking and understated sophistication.
