Caliper Slide Rule Watch

Before there were calculators, slide rules were the most common tool for quickly finding the answers to simple math problems. In watches, however, this process has gone in reverse. Decades after the advent of digital calculator watches, the Caliper Slide Rule Watch brings the classic mathematical tool to your wrist. By turning the lower crown, you move the interior ring of the rule, which wraps around a semi-transparent face through which the Miyota movement is visible. The case is made from PVD-coated 316L steel, and has a list of handy conversion factors on the reverse side. Available in two styles, it's water resistant to 100 meters.

G-Shock GPW2000 Gravitymaster Watch

It also features a bright LED illumination system, Bluetooth connection functionality, and a built-in solar power supply, so it stays charged at all times. And just like previous G-Shock releases, it's one of the most durable timepieces you can buy, featuring shock resistance and 200m water resistance.

Bell & Ross BR-X1 Black Titanium Watch

Blending high-end horology with a rugged body, the Bell & Ross BR-X1 Black Titanium Watch is a study in contrasts.

Water resistant down to 100 meters, it's finished with a woven black rubber strap and is limited to just 250 pieces.

Skagen Signatur Hybrid Smartwatch

Not everyone wants to wear a screen on their arm, yet wrist-bound notifications are handy for anyone with a smartphone. The Skagen Signatur Hybrid Smartwatch is an affordable option that gives you the latter without the former. Its sleek design mirrors the circular case in everything from the pushers to the ends of the hour and minute hands, while a Bluetooth connection lets it automatically update to the correct time and date, let you know when you get a text or call, control your music, and track your sleep and activity. Available in four different colorways.

Tiffany and Co. CT60 DLC Watch

As a company synonymous with sterling silver, pale blue, and diamonds, black isn't a color often associated with Tiffany & Co. That's the defining trait of its new CT60 DLC Watch. The latest version of the CT60, itself inspired by a distinctive Movado/Tiffany's timepiece owned by FDR, has a stainless steel, black DLC coated case with a black dial, white metal appliqué Arabic numerals, and a date window at 6 o'clock. Made in Switzerland, it's available as a 42mm chronograph or 40mm time-only model.

AMOT Modular Watch

If you opt for a modular watch, you want the convenience of several watches in one. But most don't employ as many functions and features as the Modular Watch from A Matter Of Time. The modular watch is comprised of the base, dial, bezel, and strap and each comes with at least one additional option. Both 39mm bases are powered by Seiko automatic movement, feature a sapphire glass, luminous blue hands, and all the components are easy to swap out as you transition from one setting to the next.

SFI Desert Issue Rolex Submariner Watch

For its latest modified offering, Special Forces Issue takes a modern day Rolex Submariner and remixes it into a military masterpiece. Using the classic Rolex 5517 Milsub as inspiration, SFI's DI01 Desert Issue is a 114060 Submariner that's been coated in a tactical Desert Sand finish and given a makeover with fixed military bars, custom "Sword" hands, and a rubber bezel insert with luminous markers. The watch arrives in a waterproof Pelican case on a matching tan NATO strap.

Tempus Machina 711Z Rolex GMT Master Watch

Like a classic car with modern innards, the Tempus Machina 711Z Rolex GMT Master Watch combines the looks of the 1950's "Bakelite" Rolex 6542 GMT watch with the reliable features of the current model 116710 GMT-Master II. Inspired by the brittle, signature 24-hour bezel insert of the mid-century watch, this new interpretation uses a polished sapphire insert with hand-applied luminescent numerals and indicators. But Tempus didn't stop there. The bezel was re-profiled with a "Coin Edge" teeth look, the crown guards were removed, and a black-and-red "Roulette" style date wheel was added. On top of that, the 18k gold-plated dial is as close as you'll ever get to an original "Gilt" dial, and the GMT hand — the heart of the dual time zone functionality — has been replaced with a custom small arrow hand to match the original.

Louis Vuitton Tambour Horizon Smartwatch

LV has made watches before, but never like this. The Louis Vuitton Tambour Horizon Smartwatch is the company's first connected timepiece. Built in conjunction with Google and Qualcomm using a Swiss-made 42mm convex case, it's powered by Android Wear. You'd never know it looking at the screen, which shows one of several of customizable faces based on the company's real-life watches. You also get a special app that taps into the company's city guides for recommendations and a special travel app that keeps track of flight and booking info. Perhaps most importantly for those who love the company's leather goods, you can choose from 30 different straps that interchange quickly, so you won't have to settle for a traditional monogram strap clashing with your graphite wallet.

Vague Grey Fade Submariner Watch

Vague Watch Co.'s Grey Fade Submariner gets its name from the dark grey bezel insert, meant to mimic the sought-after "ghost bezel" effect found on the faded black bezels of well-worn vintage sport watches. It's built with an automatic movement, meaning you'll never have to change a battery, as the watch is powered by the movement of your arm during wear. With a stainless steel case, a screw-down back, and a 100-meter depth rating, the watch is also rugged enough to handle some serious time in the water. On top of that, it ships with a sharp military-inspired case, watch tool, and a classic nylon NATO strap to switch out with the stainless oyster band.

Limited to just 100 examples.

A modern interpretation of the highly collectible reference 7754 "Skipperera", the Tag Heuer x Hodinkee Carrera Skipper Watch is bound sought-after itself. Its 39mm case has the same lugs as the original 35, and the regatta countdown dial has the same tri-color layout, but now with 10-minute intervals.

It's finished with a blue perforated leather strap and comes with both gray and orange NATO straps for casual wear.

Ressence Type 1 Rose Gold & Titanium Watch

Ressence's Type 1 is already considered a modern classic, thanks to its novel design that eschews hands and crowns for a series of rotating discs that indicate the hours, minutes, seconds, and day of the week.

Also present on the exclusive edition are an ivory dial with Super-LumiNova-filled engraved indications and a handsome brown leather strap.

Paul Newman's Rolex Daytona Watch

It's arguably the holy grail of vintage watches. A timepiece so influential its owner became the nickname of the model. Paul Newman's Rolex Daytona has been found. Paul Newman gave the watch to its current owner James Cox while Cox was dating his daughter and informed him that he didn't own a watch. "If you wind it, it tells pretty good time," Newman said to Cox, who proceeded to wear it daily for over a decade. It's in highly respectable condition for a watch of its age, with an original cream dial with patina, a case that's in good shape, and an inscription on the back from Newman's wife Joanne reading "Drive Carefully, Me." It will be auctioned off this October during Phillips's first watch auction in New York.

H. Moser & Cie Swiss Alp Watch Zzzz

It's not an Apple Watch. It just looks like one. A playful take on the smartwatch, the H. Moser & Cie Swiss Alp Watch Zzzz is a 100% mechanical timepiece. The dial is completely devoid of all indices and markings, letting the hour and minute hands stand alone. Powered by an HMC 324 form movement, it has a power reserve of at least four days, is limited to just 20 pieces, and serves as a satisfying rebuttal to all those who panned Cupertino's design.

MVMT Black Rose Voyager Watch

Mixing a brushed black stainless steel case with rose gold accents, the MVMT Black Rose Voyager Watch is both bold and subtle. It's powered by a Miyota movement that handles the hour, minute, and second hands, as well as the two dual time subdials. Measuring 42mm and finished with a black stainless steel mesh strap, it's an ideal size, but should you want something larger — or smaller — the Black Rose collection also includes 45 and 40mm variants in classic and chrono styles.

Rolex Oyster Paul Newman Daytona Gold Watch

One of the rarest Rolex ever to come up for sale, this Rolex Oyster Paul Newman Daytona Gold Watch is one of just three yellow gold with screw down pusher models known to exist. Beyond its rarity, highlights of this reference 6263 — nicknamed "The Legend" — include its "lemon" dial, a far cry from the ivory most commonly seen on stainless Paul Newmans, and its white subdial registers. Manufactured in 1969 and brilliantly preserved, it recently set the record for most expensive Daytona ever sold.

It's finished with a new blue and bronze fabric strap with bronze hardware and has an engraving commemorating the anniversary on the rear.

Shinola Canfield Bolt Watch

Typically when buying a watch, you're limited to just a handful of case and strap combinations. The Shinola Canfield Bolt Watch defies this logic by letting you pick from over 200 possible combinations. The clean sunray dial has three hands, no indexes, and its namesake bolt in place of the full Shinola logo. It's available in five colors and three 43mm case finishes and is powered by an Argonite 713 quartz movement. To finish it off the company's offering a staggering number of strap and bracelet options, from simple NATO nylon to alligator leather and stainless steel, ensuring you'll be able to build one to match your style.
