Phillips is honored to offer this wonderful, open-face pocket chronometer owned by Henry Graves Jr. Widely considered one of the 20th century's most important watch collectors, he is best remembered in the 21st century for his competition legendary with automobile entrepreneur James Ward Packard, to commission some of the most complicated timepieces ever produced. Graves would end up the ultimate victor, having commissioned the “Mona Lisa” of timepieces as described by Stacy Perman, author of “A Grand Complication”, the Patek Philippe Henry Graves Supercomplication. Delivered in 1933, with 24 complications and requiring over 8 years of development, it was the most complicated timepiece ever made, holding that distinction for over half a century.

Graves was born in 1868 to a prominent New York City family known for their banking and financial interests spanning railroads and cement – ​​and dynastic wealth. Following in his father's footsteps, he became an accomplished collector establishing himself as one of the most discerning and influential connoisseurs across genres. Today, Graves is recognized for his keen eye for quality and for sparing no expense to acquire some of the most exquisite timepieces ever made by brands such as Patek Philippe, Jules Jurgensen, and Vacheron Constantin.

Before Graves' pursuit of ultimate complications, he sought the highest performing, most accurate timepieces produced by the finest watchmaking brands. Always Choosing 18 karat gold or platinum, he specifically requested from brands such as Patek Philippe, the #1 rated movements from annual chronometry competitions held at the Swiss Observatories – each hand-built and hand-adjusted by the brands' best watchmakers. Equivalent to Formula 1 race cars, these “observatory chronometers” were a nod to Graves' own pursuit of perfection and excellence. Before delivery to Graves, their cases would be engraved with his family motto, “Esse Quam Videri” – "To be, rather than to seem."

The present lot is certainly one such example. Fitted with an extremely fine movement equipped with a Guillaume balance and designated “Extra Special” on its bridge, the accompanying “Extract from the Archives” confirms the watch was issued a Geneva Observatory rating in September 1920.

Consigned by the winning bidder in that 2010 auction, it has remained unused for the past 14 years and offered in the exact state of preservation as when it last appeared. The case, with hidden hinge, is very well preserved and has no signs of needless polishing with the family coat of arms remaining extremely crisp. Its enamel dial is utterly superb, a gorgeous cream color with black Breguet numerals, it features an up/down indicator at 12 o'clock typical of shipboard chronometers of the era, and is in flawless condition. Patek Philippe pocket chronometers with up and down indication are very rare in the marketplace – and even fewer are known to have been cased in yellow gold versus silver cases most often seen

Whilst the exact number of Packard and Graves-commissioned timepieces aren't known, approximately 30 have appeared on the market to-date. Accordingly, any time a Packard or Graves-owned timepiece is offered, the collecting world takes notice.

Lot 82: A Late 1800s Louis Elisée Piguet Minute Repeating Hunter-Style Pocket Watch that's included in the upcoming Phillips New York Watch Auction: X. Estimate: USD $15,000 - 30,000

Los hermanos Maulme, the Maulme brothers, were immigrants to Guayaquil, Ecuador, in the latter part of the 19th century. Arriving from Peru (or possibly Chile) as the sons of French immigrants, Enrique and Luis Maulme quickly set out to make a fortune in mining, and eventually branched into brewing and automobiles. Enrique Maulme's automobile business eventually became the sole distributor of General Motors products in Ecuador. It is no leap of the imagination that one of these brothers, flush with success, ordered this highly prestigious timepiece.

The movement was likely from noted Le Brassus watchmaker Louis Elisée Piguet, who provided ebauches of the highest complications for such notable makers as Patek Philippe, Vacheron Constantin, and Breguet. Indeed, this exact type of movement could be said to have inspired Philippe Dufour's grande and petite sonnerie pocket watch, and later the first wristwatch to feature this same complication. Michel Parmigiani, former watch restorer and founder of Parmigiani Fleurier, acquired a LE Piguet grande and petite sonnerie ebauche and created the unique piece “La Rose Carrée” in 2021.

One of only nine known examples of a possible 15 produced between 1917 and 1922, the present watch was sent to the Kew Observatory for testing in 1919, and received 89.2 marks, earning a Kew A “Especially Good” certificate. Housed within an extremely high-quality 18 karat yellow gold hunter case with 5-knuckle joints and a raised push piece, the frosted gilt three-quarter plate movement exhibits finest quality, hand-made details, such as jewels housed in screwed-in gold chatons, mirror polished bridges and tourbillon cage, and beautifully beveled gear axles.

The tourbillon escapement, of course is the star of the show. The polished steel double-arm bridge, referred to in scholarship as the “Better 1” design attributed to Sidney Better, and houses a “Better type-2” carriage with offset arms. Free-sprung and fitted with a blued steel balance wheel with terminal curve, the entire design was made for maximum timekeeping accuracy – and its Especially Good rating at Kew proves it. Beautifully preserved With its mesmerizing, eccentric tourbillon cage immediately captivating to the eye, it is an exceptional opportunity for the discerning collector.
