Fortis 647.28.71 L.01 B-42 Marinemaster Black Automatic Date Watch


by Meehna Goldsmith  

Fortis WatchesNot many people know that Fortis has a long heritage of over 100 years of continued manufacturing and many accolades to its name. Walter Vogt established the company in 1912 and in 1924 partnered with John Harwood, inventor of the automatic wristwatch. They released the first self-winding wristwatch in 1926 called the Harwood Automatic. By 1937, Fortis moved into chronographs, releasing their first one for the celebration of the 25th anniversary of the company.

Fortis has built their reputation on producing tough, functional watches that are equal to standing up to punishing environments. In 1994, Fortis put its watches through such rigors of testing that pushed the boundaries of modern physics that the Russians came calling. The Russian training facility for cosmonauts located in Star City Russia chose the watch, now called the Fortis Official Cosmonauts Chronograph, as part of their official equipment. The watch was put through the paces inside the shuttle and in space, proving its muster by keeping time like the day it was born.

Because of the association with the Russian cosmonauts, the Fortis name might initially bring up the idea of a space watch, but the brand has also mastered other environments such as aviation and maritime.

The Men’s 647.28.71 L.01 Black Automatic Date from the Fortis B-42 Marinemaster Collection is a capable and good-looking dive watch. Like most tool watches, it comes in a larger 44 mm case so that the dial has more real estate and can be easily visible underwater. The black dial features a day and date at 3 o’clock Arabic numerals with the traditional triangular marker at 12 o’clock, rounded out with baton numerals at 6 o’clock and 9 o’clock.

As required by all dive watches, the hands and numerals are swathed in luminescent material. In a stainless steel case covered in PVD, the watch has a very stealthy look that will blend right in by land or over a wetsuit.

Of course, every dive watch must have a unidirectional bezel, and the Fortis 647.28.71 L.01 B-42 Marinemaster comes with one. But what make this bezel even more interesting is in addition to the 60-minute display, a 24-hour display is also included. Most dive watches don’t have an exhibition back due to water resistance issues, but Fortis managed to get around that obstacle so you can get a view of the mechanics too.

The Fortis 647.28.71 L.01 B-42 Marinemaster comes with an automatic movement with a shock absorber and is water resistant to 660 feet.

Fortis 671.24.14 K B-42 Marinemaster Yellow Men’s Chronograph


by Adrian Herscovici  

New Stripes for an Enduring Classic

Fortis WatchesOne thing that gets some collectors excited is a new variation of a favorite watch. Fresh colors have the ability to revitalize a design and breathe contemporary air into a classic look. The latest version of the Fortis B-42 Marinemaster Chronograph mixes black and yellow – a popular color combination found in nature, in fashion and in design the world over, not to mention in watch collections from brands both large and small.

Buy Fortis 671.24.14 K B-42 Marinemaster Yellow ChronographLike other watches in the Marinemaster collection, the B-42 Marinemaster Chronograph is built for life. It starts with a stalwart movement: the ETA Valjoux 7750 automatic, a benchmark among chronographs and veritable pillar of Swiss precision and reliability.

The rugged three-part case is constructed of brushed stainless steel and measures 42 mm in diameter. The unidirectional turning bezel is both a visual and functional highlight: the combination of black and yellow is eye-catching, while the deep scalloped edges provide good grip for turning, especially underwater, where the watch is water resistant to a depth of 660 feet. There is more to the bezel: unlike most dive bezels, this one makes a full turn in 120 increments, meaning it is adjustable in half-minute steps. The pip positioned on the bezel at 12 o’clock is luminous and has a blue afterglow.

Functional aspects of this Marinemaster do not end there. The crown is substantial enough to grip and is personalized with the Fortis logo; the chrono pushers are firmly inset and well protected. Adding to the watch’s water resistance is a screw-down caseback, which is embossed with a historic Fortis motif. On the front, anti-reflective sapphire crystal provides a clear and scratch-resistant pane.

To a novice, the dial of the Fortis 671.24.14 K B-42 Marinemaster Chronograph watch might seem crowded, but it is actually clear and easy to read thanks to the sharp contrast between the white, yellow and black elements. The layout of the sub-dials is based on the Valjoux 7750 movement with a 30-minute totalizer at 12 o’clock, a 12-hour totalizer at 6 o’clock and running seconds at 9 o’clock. These stand out next to the yellow hour numerals. Toward the outside of the dial is the minute-and-second track as well as a tachymeter scale, which is positioned on the angled flange. The hands, hour markers and indices are all coated with Super-Luminova, which glows blue in the dark. The central chronograph seconds hand also has a luminous circle half way up the hand.

A tidy set-up on the dial at 3 o’clock includes the Fortis logo as well as the day and date. Both stand out well on white backgrounds. Changing the day or date is a breeze on this watch because the two arrowheads on either side of the day and date windows – one facing down and one facing up – indicate which direction the wearer should turn the crown to make quick adjustments. They might seem superfluous, but the arrowheads are convenient reminders and, in design terms, echo the shape of the traditional arrowhead index at 12 o’clock – which appears in deference to Fortis’s aviation style watches.

Since the B-42 Marinemaster Chronograph is a seagoing watch at heart, Fortis mounts the watch on a black rubber strap that fastens by way of a brushed steel folding clasp featuring the Fortis logo. But there are options to mix it up; namely, a black leather strap or steel bracelet.

Fortis Mens 635.10.11 L.08 B-42 Pilot Professional Black Dial Aviator Chronograph


by Adrian Herscovici  

A Match Made in Flight: The Fortis B-42 and the Valjoux 7750

Fortis WatchesBefore pilots had chronographs integrated into their wristwatches, they typically carried separate stopwatches for use in navigation. When the time-only wristwatch was eventually combined with a chronograph, pilots were able to satisfy both functions with one device.

Fortis fuses these two primary functions in its Fortis B-42 Pilot Professional Chronograph from the company’s aviation collections, and what better movement to salute this match made in flight than the famed Valjoux 7750, the veritable workhorse of mechanical chronographs, which like the pilot watch, is renowned for its function-over-form simplicity.

Fortis Mens 635.10.11 L.08 B-42 Pilot Professional Black Dial Chronograph Aviator Watch


The Valjoux 7750 was introduced in 1974 and features prominently in contemporary chronographs. It differs from the traditional column-wheel chronograph in that it uses a different mechanism to control the switching functions, which include starting, stopping and resetting. The significant advantage of the 7750’s design is in efficiency, both in terms of ease of assembly and ease of maintenance.

Fortis customizes the winding rotor of this Valjoux 7750 with blue engravings including the Fortis logo; the words Since 1912 Swiss commemorate the company’s founding year, while World’s First Manufacturer of Automatic Wristwatches commemorates one of the company’s finest achievements. All of this can be viewed through the watch’s exhibition caseback.

To accommodate the movement’s three-plate construction (main plate, calendar plate and chronograph plate), the two-part stainless steel case is 42 mm in diameter by 16 mm thick. The sapphire crystal has an anti-reflective coating on both sides and the caseback is screw-down. The oversized, screw-down crown adds to the watch’s overall water resistance of 660 feet.

The distinctive chronograph counter layout of the Valjoux 7750 has the 12-hour counter at 6 o’clock, the 30-minute counter at 12, and the continuous-seconds counter at 9. The chronograph hands, meanwhile, are painted orange so that elapsed seconds, minutes and hours can be calculated with relative ease.

White numbers and indices provide excellent contrast against the matte, black dial. Plenty of Super-LumiNova coats the numerals, hour markers and hands. In addition to the traditional arrowhead index and flanking dots at 12 o’clock, two other arrows appear on either side of the day and date windows – one facing down and one facing up – to indicate which direction the wearer should turn the crown to make quick adjustments. The flange has a tachymeter scale for measuring speed in conjunction with the chronograph.

This Fortis B-42 Pilot Professional Chronograph features a padded cognac-brown leather strap with white stitching that brings the black, orange and white dial elements to the fore. The strap is fitted to the case and the prong-style buckle is personalized with the Fortis crown.

This Fortis B-42 Pilot Professional Chronograph may also custom labeled through the Fortis Squadron Watch and Fortis Private Label Watch Programs.

Fortis Mens 665.13.19 L.01 B-42 Stratoliner 100th Anniversary Special Limited Edition Black Dial Chronograph Watch


by John Sealander  

One went into outer space.

100 more are now available for your wrist.

Fortis WatchesThe original Fortis Stratoliner chronograph has the distinction of being the first Fortis watch to be launched in space when it went into orbit in 1992 on board a Russian Proton rocket as one of the exhibits in the world’s first “space museum.” Even though the Stratoliner was never as popular as later Fortis space and aviation watches, this initial venture into space earned the watch a place in history and led to close cooperation between Fortis and the Russian space program. To this day, every Russian cosmonaut is presented with a Fortis Official Cosmonauts Chronograph when they complete their training at the Yuri Gagarin Space Center.

Early Fortis Stratoliner watches are prized by collectors today for their use of the legendary Lemania 5100 movement. This rugged movement could survive acceleration in excess of 7G without loss of accuracy and easily absorbed shocks and blows without stopping the chronograph second hand. When the 30 year old movement was discontinued in 2003, Fortis continued to manufacture the classic Stratoliner using an enhanced version of the reliable Valjoux 7750 chronograph movement. The Stratoliner never went out of production and eventually became part of the popular Fortis B-42 Collection.

Buy Fortis Men's 665.13.19 L.01 B-42 Stratoliner 100th Anniversary Limited Edition Chronograph WatchTo commemorate the Stratoliner’s important place in space and aviation history, Fortis has recently introduced a special limited edition of the classic Stratoliner in celebration of the company’s 100th anniversary. This handsome 42mm timepiece features a dramatic black PVD coated stainless steel case that houses the Swiss made ETA Valjoux 7750 automatic movement. The black dial and retro looking black tachymeter bezel are enhanced with the use of 18 karat rose gold accents, along with gold plated hands. The watch is equipped with a scratch resistant sapphire crystal and two rose gold pushers and a gold crown complete the elegant look.

Fortis Mens 665.13.19 L.01 B-42 Stratoliner 100th Anniversary Limited Edition Black Dial Chronograph Watch


Only 100 pieces of this exclusive limited edition timepiece will ever be produced. Each watch is water resistant to 200 meters and is fitted with a black leather or reptile strap. If you’re interested in acquiring a Fortis Stratoliner 100th Anniversary Limited Edition for yourself, you’ll want to act quickly. This exclusive edition is sure to be popular with collectors, so be sure to contact an authorized Fortis dealer immediately and reserve your Stratoliner today.
