HTD Aquatic GMT: a true GMT diver from Florence

The GMT-Master II look is the most copied silhouette in watches: a two-tone 24-hour bezel, a fourth hand, a watch that keeps two time zones straight while you cross them. Getting the Rolex version takes five figures and a relationship with a dealer. HTD, a small operation working out of a Florence laboratory, will sell you the same working idea for $1,111, shipped from Italy with the duties already covered.

HTD stands for Horological Tools Department. Federico Del Guerra and Federico Zulian founded the brand in Florence in 2020, and the Aquatìc GMT is its first GMT, built on the Aquatìc diver the brand already sells. It’s a small watch with a serious movement inside, and the movement is my favorite part of this one.

Built on the Aquatìc diver

The case is 316L stainless steel, 39mm across and 47mm lug to lug, which puts it in the wear-it-every-day class rather than the dinner-plate class. Thickness is 12.4mm including the crystal, a domed sapphire with an internal anti-reflective coating that gives the dial its soft vintage edge. Under it, the watch is still a diver: 200 meters of water resistance and a screw-down crown sealed with four O-rings.

Every version runs the same black dial. Applied hour markers are beveled toward the center, a small three-dimensional touch you notice in daylight, and the lume is Super-LumiNova BGW9 laid down in multiple layers. It glows blue, generously, on the markers and the domed hands. Its date numerals alternate red and black, odd dates in red, a tribute to the way Florence numbers its streets.

A traveler GMT, not a caller

Most affordable GMT watches use a caller movement: the 24-hour hand moves and the main hands stay put, which is fine for tracking a second office and wrong for landing in one. The Miyota 9075 inside the Aquatìc is a traveler GMT. Land, pull the crown, and the local hour hand jumps forward or back in clean one-hour steps while the GMT hand keeps home time running untouched.

That’s the trick the GMT-Master made famous, done properly, at a tenth of the price.

Inside, the 9075 runs at 28,800 beats per hour with a 42-hour power reserve, and HTD regulates every single unit in its Florence workshop before it ships. A microbrand at this price usually buys movements by the tray and cases them up. Regulating each one in-house is bench time, and bench time is the thing this segment usually skips.

Four bezels, one watch

Its bezel turns in 24 precise clicks on a new ball-bearing mechanism HTD built for this watch, so it lands on each hour with a mechanical certainty you feel through your fingertips. Four versions share the same case, dial, and movement, and the pick is purely about color.

Rosso Blu is the blue-and-red Pepsi, the one that wears its inspiration openly. Golden Brown runs brown with gold tones, the Root Beer configuration, and pairs it with a gold-framed date window. Departure Green goes green. The World Timer swaps the 24-hour scale for a black bezel engraved with city names, Florence among them, so a twist of the bezel lines up a third reference against the GMT hand.

The bracelet and the buying part

The watch rides on HTD’s 323 bracelet, a three-link steel design the brand refined for its sport watches. Ordering asks for your wrist measurement, the bracelet arrives sized, and any extra links come inside the box. It’s a small touch that saves the usual first-day hunt for a screwdriver.

Look at the World Timer twice if you track more than two zones. Its bezel carries the city ring a travel watch used before phones did the job: line a city up against the GMT hand and that city’s hour reads straight off the bezel, Florence included as the home marker. It’s the quietest of the four and the most old-school in how it works.

Buying is direct. HTD sells the watch from its own store at $1,111, the price holding the same across all four bezels, and US orders carry all tariffs and duties included in that figure. Watches ship by DHL against a signature, and the warranty runs two years and transfers to a second owner if you sell the watch on.

HTD also takes returns inside 14 days on a prepaid DHL label for buyers who change their minds. The GMT is in stock now, with deliveries running since late October, and the brand’s laboratory in Florence handles sizing, engraving requests, and service under one roof. Delivery runs three to seven business days once the watch ships.

What you give up is the name on the dial and everything that trails behind it: the dealer theater, the resale premium, the recognition at a glance.

What you keep is the function that made the GMT-Master famous in the first place, a jumping hour hand over a home-time hand, wrapped in a 39mm diver that swims, glows, and travels. At $1,111 with the tax man already settled, buy the Aquatìc for the movement and skip the waitlist entirely.
