Rado HyperChrome Ultra Light Watch

Inspired by military pocket watches from the '20s and '30s, the Rado HyperChrome Ultra Light Watch is one of the most minimal timepieces you can find. It's made from a high-tech ceramic — Code name Si3N4 — so it weighs less than two ounces, or so little you barely know it's there. It's available with a brown leather strap, but also with a brown NATO strap that speaks to its utilitarian nature. Limited to just 500 pieces.

TAG Heuer Monaco Bamford Watch

Race car bodies have transitioned from metal to carbon fiber. So has the TAG Heuer Monaco Bamford Watch. Drawing from motorsports, the team at Bamford have built a 39mm carbon body and paired it with a reinterpreted dial marked by aquatic blue highlights. The smaller size, coupled with the materials, makes it a lightweight and surprisingly stealthy choice. It's finished with a black alligator strap and is one of the more unique Monaco variants available.

G-Shock GBA800 Watch

It looks like your average G-Shock on the outside, but hidden within the signature shock-resistant shell is a fitness tracker.

Pair it with their app and it can sync up to your phone for a breakdown of your daily activity. It'll even show exactly where and when you burned your calories. The timepiece is also water resistant up to 200 meters and comes in six fresh monotone colorways.

Tudor Black Bay Fifty-Eight Watch

Named for the year when TUDOR's first diver hit the market, the Black Bay Fifty-Eight Watch offers several nods to mid-century timepieces. Most notable is the 39mm steel case, pleasing both the slim-wristed and vintage enthusiasts alike. Its black dial is complemented by gold touches on the hands, indices, and bezel, the crown tube is satin-brushed steel — a first for the Black Bay line — and the matching steel bracelet features "rivets" that call back to TUDORs from the '50s and '60s. Powered by the new Calibre MT5402 in-house movement, it's also available with a brown leather or black Jacquard fabric strap.

Tudor Black Bay GMT Watch

Building on its line of well-received divers, Tudor's Black Bay GMT Watch adds a world time function to this timeless silhouette. Its blue and burgundy matte bezel is a call back to classic GMT watches, as is the red snowflake hand that floats above the black dial and marks the time in a second zone. It's powered by the new MT5652 movement, housed in a 41mm stainless steel case that's waterproof to 660 feet, and is paired with a matching riveted steel bracelet, brown leather strap with folding clasp, or black fabric strap with burgundy band.

Optik Horizon Watch

Swiss accuracy meets progressive design in Optik Horizon Watch. The timepiece gets its name from its distinctive two-tone composite dial that rotates once every 24 hours, with the center line representing the transition from day to night. A red line on the internal bezel points to the current time and simple indices at quarter-hour increments provide all the accuracy everyday use requires. Available in four colorways, each of which has a 40mm diameter stainless steel case, domed sapphire crystal, and 45-month power reserve.

Rolex GMT-Master II Oystersteel Watch

For most watch collectors, the words "GMT," "Pepsi," and "Steel" will be enough. But the Rolex GMT-Master II Pepsi Oystersteel is far more than a simple reissue. Beyond the Cerachrom insert in red and blue ceramic, its lugs and sides have been redesigned and fitted to a five-link Jubilee bracelet. Inside its 40mm case sits a new-generation calibre 3285 movement, which is more efficient and has a longer power reserve than the prior 3186.

White Gold Rolex Daytona 6265 Watch

For decades, it was thought that only stainless steel and yellow gold versions of reference 6265 existed. Until this White Gold Rolex Daytona 6265 Watch was discovered. Nicknamed "The Unicorn" for its one-of-a-kind nature, it was manufactured in 1970 and delivered to a German retailer in 1971. In the years since, the special order item has returned to Rolex on several occasions — most likely for service — and remains in outstanding condition. Its current owner purchased it eight years ago but is now putting this rare piece up for auction. It will go under the hammer at the Daytona Ultimatum event in Geneva on May 12, with the proceeds going to benefit the group Children Action.

Fitbit Versa Smartwatch

Thinner and lighter than the smallest Apple Watch, the Fitbit Versa Smartwatch is a fine option for those not tied to the iPhone. It ditches the prior Ionic's polarizing angular form for a softer squared circle, yet retains key features like 24/7 heart rate monitoring, on-device fitness coaching, GPS, and activity tracking, including in the water and while you're asleep. It comes in four colors and in standard and NFC-equipped Special Edition models.

Garmin Tactix Charlie Watch

Designed specifically for tactical use, the Garmin Tactix Charlie Watch is rugged enough for the military yet stylish enough for everyday use. In addition to pre-loaded, full-color Topo mapping, it also offers mission-critical features like Jumpmaster support, GPS and GLONASS, and waypoint projection. Its black DLC-coated titanium bezel has UTC markers that work in conjunction with the always-on, 1.2-inch screen, while the opposite side houses a built-in heart rate monitor. With 12 days of battery life in smartwatch mode and up to 20 hours of GPS wayfinding, you won't need to worry about charging mid-journey, either.

Hermes Slim d'Hermes GMT Watch

Instantly identifiable as a Slim model thanks to its Philippe Apeloig-penned typeface, the Hermès Slim d'Hermès GMT Watch adds a secondary hours subdial to its sleek design. Its powered by a Manufacture Hermès H1950 movement measuring just 2.6 mm thick, which works in concert with a 1.4 mm GMT module. Each piece of the dial — indices, GMT dial, and date counter — has its own finish to add visual interest and sits inside a palladium case measuring 39.5 mm around and just 9.48 mm thick. Finished with a matte graphite alligator strap crafted in Hermès' workshop and limited to just 90 examples worldwide.

Oris Source of Life Watch

Inspired by water — the River Rhine in particular — the Oris Source of Life Watch is a special version of the Aquis diver. Most notable on its deep blue face is the circular date scale and the white indicator that takes month-long laps around the dial to show the date. Its 43.5mm stainless steel case is enhanced by a gray tungsten bezel insert and a backplate embossed with a map of the Rhine. It's finished with either a stainless steel metal bracelet or gray rubber strap, and is limited to just 2,343 pieces to reflect the sea level height of Lai da Tuma, the source of the Rhine.

Calibre 11 x Tag Heuer Jo Siffert Autavia Watch

One of the first F1 drivers signed by a watch company, Jo Siffert famously wore a white-dial 1163T Autavia. Drawing inspiration from it and the three-register 73633, the Calibre 11 x Tag Heuer Jo Siffert Autavia Watch recreates the essence of these classic timepieces with modern components. It's based on last year's CBE2110, with a 42mm steel case, modern Calibre Heuer-02 movement, opaline white dial, black sub-dials, and blue central hand and markers. Finished with a bidirectional bezel with black aluminum insert, accompanied by both a "grain of rice" 7-row steel bracelet and black leather strap, and limited to just 100 pieces.

Vintage Heuer x Bamford Tag Heuer Monaco Watch

"The Dark Lord" refers to a rare Monaco from 1974. Among the first PVD-coated timepieces, questions about the durability of its finish led to its rarity. The Vintage Heuer x Bamford Tag Heuer Monaco Watch was created with it in mind. The red hands are now orange, the subdials white with checkered flag elements below, and the crown is now on the left, but it's otherwise very similar. Finished with a perforated black leather racing strap with orange stitching.

Porsche Design 1919 Chronotimer Flyback

Inspired by the design and functional aesthetics of the Porsche 911, the Porsche Design 1919 Chronotimer Flyback is the latest in the automaker's series of well-designed timepieces. Its COSC-certified Porsche Design Werk 01.200 movement is made in-house and sits within a sleek titanium case with minute indices positioned on the outer edges of the dial in lieu of a traditional tachymeter bezel. Arriving in stores this September.

Bell & Ross 03-92 Horoblack Watch

Named for Bell & Ross' concept of using matte micro-blasted steel for the 42mm case and dial, the BR 03-92 Horoblack Watch places legibility above all else. Cutouts for the numerals and indices let the black Superluminova layer underneath shine through, and a BR-Cal.302 automatic movement provides lasting accuracy. Finished with a black rubber strap and limited to just 999 examples.

Tag Heuer Carrera Heuer 02 Watch

In celebration of the 55th anniversary of the Heuer Carrera, Tag has created an all-new movement. It can be found in the Tag Heuer Carrera Heuer 02 Watch.
