Piaget Protocole Jumbo 90154 – 18K Yellow Gold with Silver Roman Numeral Dial, Manual (Ultra-Thin)

This Piaget Protocole ref. 90154 is a refined example of Piaget’s mastery of ultra-thin design, presented in elegant 18K yellow gold with a silver dial accented by bold black Roman numerals. The minimalist casework and timeless dial layout embody the maison’s commitment to sophistication and clarity.

The rectangular case with gently beveled corners frames the silver dial beautifully, where applied Roman numerals create a striking contrast. Slim gold dauphine hands complete the composition, ensuring excellent legibility while maintaining a sense of understated luxury. At 26 × 30.5 mm, the 90154 wears larger than its sibling ref. 9154, offering a more versatile size for contemporary collectors without compromising its sleek ultra-thin form.

Inside, the watch houses Piaget’s legendary manual-wind ultra-thin movement—Caliber 9P or its refined successor, the 9P2—celebrated for its reliability and pioneering slim profile. A leather strap and original 18K yellow gold Piaget buckle complete the ensemble.

Classic yet distinctive, this Protocole offers collectors the rare combination of Roman elegance, ultra-thin engineering, and the larger case dimensions that make the 90154 so desirable compared to the more frequently seen 9154.
