Armin Strom this week introduces Lady Beat, the independent Swiss watchmaker’s first watch designed with feminine customers in mind. And while the new collection aesthetically echoes Armin Strom’s existing Gravity Equal Force collection, with its open-dial three-bridge design, Armin Strom has built an all-new, less-complicated caliber and has placed it within a fairly thin new 38mm case, a first for the brand.

The 38mm case diameter of Lady Beat is a first for Armin Strom.

Armin Strom explains that the Lady Beat was designed in concert with female design consultants, who sought to answer the question: “What does a woman desire on her wrist?”

Thus, the new Lady Beat features an off-center dial that displays only a minute and hour hand with no markers except the company logo at 12 o’clock. This contrasts with the classic three-hand display with small seconds found on the Gravity Equal Force.

Armin Strom’s new Lady Beat is characterized by soft, moon-like shapes.

And, instead of powering the watch with a visible micro rotor (as on the Gravity Equal Force) Armin Strom has developed a full-sized central rotor and placed it on the back of the new Caliber ALA20.

And while the wearer can still eye the movement’s vibrating balance directly on the front of the Lady Beat, Armin Strom has removed the stop-works declutch system and novel ‘equal force’ motor barrel from the new caliber. This allowed Armin Strom to create a caliber for Lady Beat that is thinner than the movement inside the existing Gravity Equal Force.

Also contributing to the Lady Beat’s “soft shapes” design brief, Armin Strom replaced classic lugs in favor of an integrated strap. Circles and semi-circles replaced the earlier design’s angular shapes throughout.

“These soft, moon-like shapes fill the optics of this watch,” explains Armin Strom co-founder Claude Greisler. “Look closely and you will see a half-moon-shaped plate sharing the watch’s lower level with the mechanical elements, while a full moon-shaped subdial sits atop it.”

The back of the Armin Strom ALA20 shows the new full-size, decorated rotor.

Conclusion: Armin Strom succeeds on its own terms with its first feminine watch as it avoids the all-too common watch design trap of simply adding gemstones to a smaller version of an existing model.

At the end of every issue of International Watch, we present a one-page item about a watch with a particularly handsome rear view. It’s a popular feature we’ve published for many years­– in print only and within our online full-on digital editions. 

If you’re not subscriber to our quarterly print publication, perhaps you haven’t seen this feature. If you haven’t, below we remedy that sad state of affairs with just a few of our more recent BackStory items.

Enjoy the view.

 

BackStory: Armin Strom Masterpiece 1 Dual Time Resonance

Even from the back of this unusual 59mm x 43.4mm oval titanium case, Armin Strom’s Masterpiece Dual Time Resonance looks like no other wristwatch. While on the front you’d see a dual-time display, a 24-hour dial and two oscillators, from the back the view underscores that four barrels power these movements. As they delightfully unwind simultaneously, they become synchronized.

As a result of this resonance, a physical phenomenon, the watch creates a highly stable timekeeping rate that heightens overall precision. Resonance, a technically difficult (and hard to regulate) technique used by only a few other watchmakers, also means the watch is more efficient and is less prone to shock-inflicted error.

Indeed, Armin Strom say that its own laboratory testing has revealed gains in precision of 15-20% for two COSC chronometer-level regulated movements placed in resonance.

Armin Strom says that its Resonant Clutch Spring (which was initially developed for an earlier watch called the Armin Strom Mirrored Force Resonance) can take up to ten minutes to synchronize the two systems. To further back its claims regarding the technology, the CSEM (Centre Suisse d’Electronique et de Microtechnique) has officially certified Armin Strom’s resonance system based on the clutch spring as being a true system in resonance.

As is evident in this back view, Armin Strom has underscored its technical proficiency with and equally impressive high level of finish on the Caliber 17 ARF bridges and plates.

BackStory: Greubel Forsey QP à Équation

Not long ago, Greubel Forsey debuted a red gold version of its QP à Équation, an exquisite ultra-complicated timepiece with complete perpetual calendar, tourbillon and equation of time function.

The watch, which was awarded the Grand Prix d’Horlogerie de Genève award for the best Calendar in 2017, utilizes a type of ‘mechanical computer’ to manage all the changes in the displays.

This ‘computer,’ which is Greubel Forsey’s seventh ‘invention,’ is an entirely integrated twenty-five-part component composed of a stack of cams with movable fingers that shift the indications on the dial and caseback. The month’s cam changes the month (seen on the front of the dial).

But at the same time, different cams within that stack moves the Equation of Time disc, the year indicator and the seasons indication disc on the back, which is the focus of this issue’s Backstory page.

With it color-coded indicators, the Equation of Time display is the most visible of the back displays. . Essentially, the Equation of Time is the conversion factor between solar and mean time. This still rarely made complication seeks to distinguish the difference between solar time and mean time, which can vary from a few seconds to as much as sixteen minutes during the year

Greubel Forsey’s QP à Équation makes these calculations internally. The watchmaker-led construction team created an easy-to-read, color-coded display of the results on the caseback. The red portion shows when the sun is ahead of the solar mean time while the blue means the sun is behind solar mean time.

On the number scale, you see how many minutes the time is behind or ahead. The other colors show the seasons, the months are indicated using letters and two semi-circles show the equinoxes. An also-rare four-digit indicator displays the year.

And finally, if you’re wondering how all these calculations are made, feel free to watch the ‘mechanical computer’ itself, which is visible directly below a sapphire disc.

Movement: 36.4 mm by 9.6mm, 624 parts total w/86 tourbillon cage parts, flat black-polished steel tourbillon bridges, 75 olive-domed jewels in gold chatons, two coaxial series-coupled fast-rotating barrels (1 turn in 3.2 hours), 21’600 vibrations/hour, with a power reserve of 72 hours, Phillips terminal curve, Geneva-style stud, nickel silver main plates, frosted and spotted with polished beveling and countersinks, straight-grained flanks, nickel-palladium treatment, 4 engraved gold plates,

Armin Strom this week releases a rose gold version of its Gravity Equal Force, an innovative time-only design with an unusual constant-force mechanism.

The Armin Strom Gravity Equal Force, now with a black dial and a rose gold case, bridges and hands.

The watch, which Armin Strom debuted in steel last year, features an in-house movement that takes a cue from high-precision pocket watches of yore. The watch’s ASB19 automatic movement features a motor barrel (where the mainspring resides) that stays locked after the watch is wound, creating a more precise arbor to rotate and drive the gears that move the watch’s hands.

Effectively, the watchmakers at this independent Swiss atelier added a stop-work de-clutch mechanism to the automatic watch, driving consistent power to the balance.

As Armin Strom explains “it is clear that it is a demonstrably better system as it is more precise and stable during operation of the movement. Armin Strom’s watchmakers built on this idea to create an entirely new watch.”

Retro-futuristic

The Gravity Force debuted with a steel case last year as an update to the Armin Strom Resonance Clutch Spring that first demonstrated the brand’s retro-futuristic approach to delivering constant force within its automatic movement.

This newest rose gold-cased version brings along a bit of luxury to what remains a technically focused watch.

The Armin Strom Gravity Equal Force in a steel case debuted in 2019.

When it debuted, the watch’s 41mm case was a new size for the brand. That size remains on this new model, as do the dominant three bridges that echo the vintage pocket watch inspiration behind the movement’s design. Here the bridges are gold, creating a luxurious contrast with the black dial.

The Armin Strom Gravity Equal Force in rose gold is priced at $26,600.
