Valjoux 7750: The Story Of The World's Most Famous Chronograph Teddy Baldassarre

Valjoux 7750: The Story Of The World's Most Famous Chronograph

The Valjoux 7750 chronograph caliber has been a mainstay of the Swiss watch industry for more than 50 years, finding its way into hundreds of watch models, under many dozens of names, and providing the technical base for numerous high complications over the years. Why is it so ubiquitous and still such an enduring presence in the watch world today? Here is a brief history of the "workhorse" mechanism that became the world's most famous and familiar chronograph movement.   Valjoux 7750 Roots: The Vallée de Joux   Sunset over the Vallée de Joux In actuality, the origins of the Valjoux 7750 go back much longer than the half-century it has actually been on the market. The company that came to be called  “Valjoux” started up at the very beginning of the 20th century, taking its original name, Reymond Frères SA, from its founders, brothers John and Charles Reymond. The company, which specialized in making mechanical chronograph movements for military and sport-oriented timekeepers, changed its name in 1929 to Valjoux - a shortened reference to the scenic Vallée de Joux in Switzerland, where it and many of its client watchmakers were located. The firm’s most successful and historically impactful creations included the manually wound, column-wheel-driven, monopusher Caliber 22, in 1914, and its even more significant successor, the smaller, longer-lived Caliber 23, in 1916. In honor of the founding brothers' surname, Valjoux movements were inscribed with a shield em...

Ollech & Wajs Introduces the Rallychron Coupe Des Alpes, a Limited Edition Paying Tribute to the History of Rally Racing

Though the more famous forms of rally racing would come later in the 1970s and 1980s, the ‘50s and ‘60s hosted some of the most daring, grueling, and downright perilous rally races in history. Without the comforts and safety considerations of our modern cars, rally drivers in the “golden age of motor racing” were just a few layers of sheet metal away from careening off mountain faces and flying into crevasses, paving the way for even more extreme rally categories, like Group B, to follow. In a celebration of the raw emotion of the Coupes Des Alpes, or “Alpine Rally”-one of the most hairball (and scenic) rally races of the midcentury-Zurich-based watchmakers Ollech & Wajs have partnered with automotive event organizer Rallystory to create the Rallychron “Coupe Des Alpes” Edition chronograph.  Founded in 1956, the Swiss brand has based the design and functionality of the Rallychron on their own competition timers from the 1960s. The brushed 316L stainless steel case measures in at a sporty 39.5mm in diameter and 15.3mm in thickness; appropriate sizing for both legibility at high speeds and comfort in high-endurance situations, like motorsport. Twin pushers and a screw-down crown fill out the heritage-style construction of the case, while the date is manipulated with a pusher at the 10 o’clock position. The unidirectional bezel is PVD-coated in black and features a tachymetric scale and inscriptions of “11 perfect lap times”, a fun motorsport Easter...

The Batavi Marine Chronograaf Conjures the Scent of Summer Worn & Wound

The Batavi Marine Chronograaf Conjures the Scent of Summer

As someone who lives within a mile of the Pacific Ocean, the smell of the sea is one of comfort to me. Naturally, this leads me to like candles and fragrances that have a hint of that crisp aquatic breeze. Of course, this has little to do with watches; or at least I thought it did. But Amsterdam-based microbrand Batavi has launched a yacht-inspired fragrance and wristwatch pairing that evokes the ocean in all its aesthetic and olfactory glory, so you can bring that sweet, salty scent with you in more ways than one.  The Marina Chronograaf lineup introduces four variants, each with identical specs but relatively singular designs. To start, each Chronograaf measures in at 46mm lug-to-lug, and a 38mm stainless steel case with 13.5mm of thickness conveys a sporty silhouette. Each model features two subdials, a running seconds and a 30-minute counter at the 9 and 3 o’clock positions respectively, a railroad track around the dial, and hands that lay somewhere between GMT, chronograph, and diver styling. Inside, a hand-wound Seagull ST1901 movement keeps the yacht-timer functionality of each reference ticking and promises a 45-50 hour power reserve. Fifty meters of water resistance, a domed sapphire crystal, see-through caseback, and stainless steel quick-release bracelet round out the package. Four dial options are available, and each colorway is about as distinct from the next as is possible. “Sunrise” features a cotton candy-esque combination of blue and pink, with a gr...

Hanhart Introduces New Versions of the ES 415 Chronograph at a Launch Event in their Historic Factory Worn & Wound

Hanhart Introduces New Versions of the ES 415 Chronograph at a Launch Event in their Historic Factory

Last week, Hanhart invited 60 guests to their workshop in Gütenbach, located in the Black Forest region of Germany. The schedule for the day was packed, beginning with a factory tour, an 8 kilometers long Black Forest hike, a Hanhart Museum tour, and finally the unveiling of two new 415 ES chronographs.  Felix Wallner and Simon Hall, co-managing directors of Hanhart, guided us through the factory and museum tour. The Gütenbach workshop opened in 1934 as the second production facility for Hanhart. It is now their only manufacturing location. It is impressive that this workshop has been in continuous production since 1934. There is a sense of authenticity, and you can almost taste the oil accumulated over eight decades.  Simon took us to the first floor where the raw parts are made. Hanhart is in a unique position as a watch company since they manufacture mechanical and quartz stopwatches along with wrist watches. The machines are from the 1960s, but according to Simon, they outperform the modern machines in terms of repairs and total cost of ownership. These machines are used for making pinions, wheels, mainplates, and more. Hanhart manufactures 90% of the parts for their mechanical stop watches in this workshop.  Hanhart in the past manufactured more stopwatches than wrist watches. In 2007, they made 20,000 stop watches, but this number decreased significantly as the demand cooled. Simon says that demand is again picking up with annual production of approximately 5,00...
