Introduction
Founded in 1874 by a young 19-year-old in the village of La Côte-aux-Fées, Piaget was originally nothing but a means for Georges Piaget to earn some extra money as he worked on movements and watches during the winter. After decades of producing watches for other brands, it was not until 1943 that the watchmaker would begin to sign their own watches and develop as the famed watchmaker that they are today. From then on, Piaget began to experiment with ultra-thin watches and push both horological and design boundaries, which eventually led to the brand expanding into jewelry in 1959, perhaps the brand’s best-known avenue today. With their impeccable craftsmanship, audacious style, and dedication to the spectacular, Piaget’s timepieces and jewelry began to coalesce, resulting in timepieces much like the Protocole ref. 5194 that we have here, which became a signature offering from within Piaget’s catalog. Boasting an 18kt yellow gold rectangular case measuring 25mm wide and 28mm tall with a lug-free design and an interesting vertical ‘tapestry’ pattern engraved down its entire front, the Protocole is an iconic piece of Piaget design. However, while the ref. 5194’s case is unique; this example’s electric blue lapis lazuli stone dial is what truly sets it apart. A stunning result of Piaget’s incredible work with stone dials, this timepiece likely resulted from Piaget’s Style Selector program where clients could pick from a variety of dials, bracelet options, case finishes, materials, and more for their watch. These stone dial Piaget offerings have become increasingly sought-after, and this lapis lazuli stone dial Protocole ref. 9154 is a perfect reminder of why collectors have flocked to them in recent times.

THE DIAL
A solid piece of blue lapis lazuli stone with golden painted Roman numerals, this Protocole's dial is a stunning reminder of Piaget's Style Selector program, whereby collectors could personalize their watches with different dials, strap options, and much more.

THE CONSTRUCTION
While its 28mm long case might seem small, the Protocole's lug-free design means that its case wears larger than one would expect, with its big dial filling as much space as possible.

TIMING MACHINE READOUT

Condition
The watch is in overall excellent condition. The yellow gold case has well-defined ribs on the front, with gentle aging visible on the edges. There are a couple of marks in the joint between the mid-case and case back from opening. The case back has very crisp engravings and a clear hallmark, with an additional hallmark on the case side that remains very sharp. The blue lapis dial is excellent, with no cracks or fissures, and the gold hands are very clean. The watch is fitted with a black alligator strap with a gold Piaget buckle, both in excellent condition. It comes with an Analog Shift box, booklet and warranty card.
Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, the exotic skin strap will have to be removed.
Our Perspective
A great reminder of how their Style Selector program enabled them to create beautiful timepieces that have stood the test of time, this Protocole ref. 9154 showcases how elegant design and incredible craftsmanship can combine to create a beautiful watch that is truly timeless.
