Our Favorite Complicated Watches Of 2025

Sometimes we overlook the power reserve indicator as a complication in a watch — but indeed it is and Hamilton outfitted one of its most popular watches with a power reserve indicator on the dial thus setting the new Khaki Field Power Reserve to take its place among our favorite complicates watches of 2025. You will recognize this watch for bearing so many of the hallmarks of the Khaki Field Mechanical but with the added gas-tank indicator style gauge at the nine o’clock portion of the dial. It’s 40mm in diameter and a touch under 12mm in case height and boasts a new movement under the hood by way of the H23 manual winding caliber with 80 hours of power reserve and a slipping spring that allows for winding to exceed the manual maximum in a “quirk” that also serves to aid the watch’s power reserve indicator to account for shocks and resynchronize itself. Overall this is the Khaki Field style we know and love with sand-blasted cases, old radium lume, NATO-style straps, as well as white and black dials — only now it’s more complicated which, to us, is a very  cool thing at just around the $1k mark. — Danny Milton

Not to count the brand out, but I don’t think anyone expected Nomos to deliver one of the most beloved watch releases of 2025. But there’s no way around it – the Club Sport Neomatik Worldtimer is a roaring hit. In addition to its range of limited edition colorways, the mix of streamlined design with just the right amount of fun and play is really what has made this watch so successful, standing out from the pack of rather conservative watch releases that dominated this year. Changing between cities is easy via the pusher at two o’clock, while the second time zone is displayed in the subdial at three o’clock. All this is made possible thanks to the in-house DUW 3202 automatic caliber, which is equipped with the brand’s novel swing-system and has a power reserve of 42 hours. — Erin Wilborn

In a move that probably few fans of its motorsport-chronograph-heavy lineup saw coming, TAG Heuer introduced a new watch with a cleverly designed moon-phase complication, the Carrera Astronomer, at Geneva Watch Days 2025. The new model — offered in three versions, two of them limited editions — pays a sort of thematic tribute to the first Swiss wristwatch in space, which happens to be a Heuer stopwatch strapped to the wrist of John Glenn during his 1962 mission aboard NASA’s Friendship 7 spacecraft. The dial’s dominant element is a moon-phase display at 6 o’clock — a large rotating disk with seven illustrated moon-phase stages flanked by two arrows calibrated for daily motion. Every night at 1:00 AM, the disk advances in synchronization with the moon’s actual 29.5-day cycle for perfect rhythm based on scientific precision. The 39mm case, in either steel or two-tone steel and gold, houses the new TAG Heuer Caliber 7, which stores a lengthy 56-hour power reserve, and does its duty behind a solid caseback engraved with the image of an astronomical observatory. The watch comes on either a tonally matched leather strap or a steel bracelet that echoes those used by the watchmaker in the Space Race heyday of the 1960s. — Mark Bernardo

The Audemars Piguet  Royal Oak Extra-Thin Selfwinding Flying Tourbillon Chronograph RD#5 is the last watch to be released in their Research & Development series. The technically remarkable watch fits a flyback chronograph and tourbillon in a slim movement that measures 31.4mm wide and just 4mm thick. This highly complicated “Jumbo” Royal Oak case itself comes in at just 39mm wide and 8.1mm thick which is just about how much the time-only version measures. Make sure to read that last sentence again to understand just what an accomplishment this watch is. Just 150 pieces will be made, making the RD#5 a true rare bird. — Bilal Khan
