The perennial watch event returns to Geneva. Here, we'll highlight the biggest watch announcements of the year. So, to kick things off, we begin with the brand that's always on everybody's lips (and wrists): Rolex. More specifically, the Rolex GMT-Master II in Oystersteel in a different colourway.

Rolex returns with a fresh new paint of some of its most iconic models. Like, the GMT-Master II in Oystersteel. If you were expecting the "Coke" version (red and black bezel), you'd be disappointed. But then you'll be elated because the GMT-Master II now arrives in a Cerachrom bezel insert (first introduced last year), either in grey and black ceramic. This colour contrast brings to mind the changing of day and night. Not a bad thing to ruminate, if you're staring at the face of time. There are moulded, recessed graduations and PVD-coated numerals on the insert that makes it easy to read.

The Oystersteel alloy is nothing to sneeze at. This material is highly resistant to corrosion and shocks and even with the onslaught of time, it'll still offers that same lustre as when you first bought it. Opt for either the Oyster bracelet or Jubilee bracelet. Another colour pops out, set against the black lacquer dial, the 24-hour hand displays and the GMT-Master II inscription are in a striking green. According to Rolex, the green is supposed to "highlight our connection to the world.

Similar to other the other timepieces in the line-up, the GMT-Master II has a 40mm case and a Calibre 3285 movement for different timezones.

After Montblanc launched its Iced Sea Collection in 2022 (y'know the ones with the glacier dials), the brand gives us the newest addition: the 0 Oxygen Deep 4810. That is a very specific number, you might say. But "4810" is a mainstay of the brand—that is the height in metres of Mont Blanc, the highest mountain in the Alps. For this venture, the 0 Oxygen Deep 4810 holds claim to being water-resistant at the depths of 4810 metres. (For context, this is almost half of the depth of the Mariana Trench at 10,909m.)

Given that it's able to withstand the depths, it makes sense that the 0 Oxygen Deep 4810 is housed in a titanium case and shielded screw-down crown.

Like the other Iced Sea timepieces, the dial of the 0 Oxygen Deep 4810 is inspired by the Mer de Glace, a valley glacier. According to the presser, the dial showcases an "interlocking network of crystals that have been frozen in time for millennia". Like the Iced Sea line, the dial's look is brought about via gratté-boisé—a tedious polishing effect that doesn't remove any of the material.

While the dial is a sight to behold, the caseback reveals a 3D-engraving of what you see under a sheet of ice. Created by a laser-generated oxidation that gives the caseback an otherworldly glimpse, a contrast of colour and texture.

If you're attempting to explore the ocean depths, illumination is a must. White Super-LumiNova acts as photoluminescence on the hands, indexes and a dot at 12 o'clock. Montblanc's COSC-certified automatic MB 29.29 movement, ticks away inside; with five days of power reserve. The Iced Sea 0 Oxygen Deep 4810 joins the ranks of Montblanc's “Zero Oxygen” timepieces that are made without any oxygen to ensure a more precise and longer performance; as well as the elimination of fogging.

Rounding up the watch is an interchangeable black rubber strap that's tapered in a V-shape and can be easily adjusted directly on the wrist.

Fifty-five years after the launch of the TAG Heuer Monaco, the brand decided to shake things up. And it lies in the keyword: "rattrapante" (French for "catch up"). It's a chronograph movement that's difficult to manufacture. TAG Heuer's repute is built upon its split-seconds rattrapante function during the early days of motorsports. It is this complication that would lead to some of TAG Heuer's best chronograph mechanisms like its newly announced Monaco Split-Seconds Chronograph.

In the early days of motorsports, TAG Heuer was hard at work in mastering the split-seconds. Introduced in 1916, its Mikrograph was the preferred timekeeping device with a recording down to 1/100th of a second. Then came the Microsplit, another rattrapante also accurate to 1/100th of a second. The iconic 11.402 model would arrive later, this time capable of measuring time with 1/10th of a second accuracy.

The 11.402 model was Jean Campiche of Scuderia Ferrari fame and then in 1989, TAG Heuer gave us a quartz split-seconds chronograph wristwatch that was popular among racing legends like Ayrton Senna, Gerhard Berger and Michael Schumacher.

This brings us to the split-seconds chronograph: TAG Heuer's Monaco Split-Seconds Chronograph.

The distinctive square-shape dial, the split-seconds innovation... it's a match-up that's a long time coming. Constructed from lightweight grade-5 titanium and sapphire crystal, you can peer through the domed sapphire crystal to see its inner workings. Within the Monaco Split-Seconds Chronograph is the TH81-00 calibre, that's developed with Vaucher Manufacture Fleurier. Not only is this a precision in timekeeping, it's also one of the lightest chronograph movements ever crafted by TAG Heuer. It comes in two colourways: a racing red or classic Monaco-blue.

The price tag for this is (does a spit-take) a whooping USD138,000 but with a complication like a split-seconds movement, it may be worth every coin.
