Audemars Piguet’s 150 Heritage is a Universal Cultural Calendar

Audemars Piguet celebrated 150 years of existence in 2025, but its celebrations have continued into the new year with the 150 Heritage Pocket Watch. While many large ultra-complicated pocket watches are exercises in nostalgia, the 150 Heritage is a modern marvel of micro-mechanical engineering with never-before-seen functionality inside a surprisingly compact 50 mm case. Initial thoughts Few brands can match Audemars Piguet’s track record of producing Grand Complication pocket watches, but the 150 Heritage surprises by adapting a calibre originally intended for the wrist. A complicated pocket watch with a simple name, the 150 Heritage is built around the cal. 1150, a newly developed hand-wound movement that adapts the architecture of the ambitious cal. 1000 developed for the Code 11.59 Universelle, and as such it includes past RD-series innovations. That said, the differences between the Universelle and the 150 Heritage are quite significant, thanks to an intriguing new feature: a hinged mechanical calculator, isolated from the movement. The intricate system is housed inside the case back and allows the user to effortlessly cycle through dates across any year to be able to read a surprising number of culturally-relevant dates based on lunar, solar and lunisolar cycles.  The device feels a bit like a time machine, as the lucky owner can go into the past or look into the future and find out the exact dates of Catholic Easter, Ramadan, Equinoxes and many others, along with...

The Haim Annum, a New Annual Calendar, is the Brand’s Most Ambitious Watch Yet Worn & Wound

The Haim Annum, a New Annual Calendar, is the Brand’s Most Ambitious Watch Yet

The Chicago based brand Haim celebrates their five year anniversary this year with what is certainly their most ambitious watch to date, the Annum. When brand founder Zakir Miah showed me an early prototype of the watch months ago at a Windup Watch Fair, I was surprised and impressed that he would even think to attempt making a watch with such a niche complication. It resets the brand in some ways, and will likely force people to consider Haim in a different way.  As surprising as an annual calendar from Haim is, if you pull back far enough, there were signs that Miah wanted to move the brand into a slightly higher end and more refined direction going back a few years. The Legacy Automatic, for example, featured a custom decorated movement by an American company, Maryland Watch Works, and the whole watch was a significant step up in terms of finishing and build quality compared to prior efforts. But the real shift came with the Viajero Worldtimer released last year. This watch featured a rather clever modification of a common Seiko-made GMT caliber, replacing the hand for the second time zone with a cities ring akin to what you’d find on a classic world timer. The old-school “globe” dial was meant to recall the most famous worldtimers from the Jet Age, and while the Viajero doesn’t have nearly the watchmaking complexity of those timepieces, it was able to mimic the style of those watches to an impressive degree when you consider the price tag of $799. The Annum ar...

First Look - The Return of Urban Jürgensen, and the New UJ-1 Tourbillon, UJ-2 Time-Only and UJ-3 Perpetual

Zenith Introduces a Chronomaster Original Triple Calendar with a Lapis Lazuli Dial Worn & Wound

Zenith Introduces a Chronomaster Original Triple Calendar with a Lapis Lazuli Dial

One of my favorite releases from Watches & Wonders (and one of the best watches Zenith has made in years, in my opinion) was the G.F.J., a study in blue and a celebration of the brand’s 160th anniversary. The G.F.J. is something of a no-expenses-spared dream watch, with a platinum case and optional bracelet that basically doubles the price (because why not?) as well as a finely finished movement and loads of history built into the watch’s story, with a focus on the brand’s historic pursuits in chronometry. When I had that watch on my wrist I wondered how the G.F.J. line might expand, and if this watch was an opening salvo in a more ambitious series of releases to come. I don’t know that we have any answers to those questions, necessarily, with the release of the Chronomaster Original Triple Calendar Lapis Lazuli today, but there’s certainly some connective tissue between Zenith’s newest novelty and the G.F.J. we saw a few months ago.  Looking at the latest Zenith Triple Calendar, it’s impossible not to notice a certain aesthetic similarity to the G.F.J. Both make prominent use of lapis lazuli, one of the most common precious stones used in watchmaking. On the G.F.J., lapis is what makes up the majority of the dial space, with the stone in the main dial nicely complementing the blue mother of pearl in the subsidiary seconds. On this new Triple Calendar, the lapis is truly the star of the show, dominating the dial and only yielding for the three subregisters i...
