Five Reasons Why We Love The Speake-Marin One&Two Openworked Flying Tourbillon

The only timepiece to feature a flying tourbillon at 1:30, the Speake-Marin One&Two Openworked Flying Tourbillon breaks away from the codes of traditional watchmaking.

The Speake-Marin One&Two Openworked now has a 60-second flying tourbillon, but you won’t find it in the traditional position of 6 o’clock. It is incorporated into the movement at 1:30 – a first in the watch industry.
 


1. A Movement In Center Stage

The Speake-Marin One&Two Openworked Flying Tourbillon is powered by the caliber SMA05, which is part of the brand’s SMA proprietary movement family. It has a 72-hour power reserve and an accuracy of -/+ 4 seconds per day that is particularly impressive for a tourbillon movement.
 

What makes this movement stand out from the crowd is the aesthetic balance between the engraved barrels, the micro-rotor, the power reserve indicator at 7:30, and the 60-second flying tourbillon at the unique position of 1:30.
 

All of the timepieces in the Openworked collection feature a complication at 1:30 such as the Openworked Hours & Minutes with its small seconds at 1:30, the Academic Metallic Blue with its micro-rotor and small seconds at 1:30, and the Speake-Marin One&Two Openworked Dual Time with its small seconds indication and retrograde date, also in this unusual position.
 

2. The Challenge

Why is a tourbillon cage at 1:30 such a big deal? How difficult can it really be to change the position of the tourbillon?

Well, is it is not as easy as it looks. Explaining the challenge to Watchonista, the brand’s CEO and President Christelle Rosnoblet said:

“Placing the tourbillon at 1:30 demonstrates Speake-Marin’s watchmaking skills. It is actually a real constraint, in terms of movement development, since the small seconds at 1:30 has to go through the time setting gears. It required a re-design of the whole movement starting from this constraint.”
 

3. Looking Into The Dial

The caliber SMA05 is constructed of different materials, colors, and finishes to offer a visually arresting aesthetic. The tourbillon cage is covered by the iconic Speake-Marin rotor in red gold, while the main plate has been micro-blasted and given a black finish to bring depth to the dial. The bridges have been finished with sharp edges to counterbalance the roundness of the case and barrels.
 

“The Speake-Marin One&Two Openworked Tourbillon reflects our Haute Horlogerie vision where we twist traditional fine watchmaking codes in displaying tourbillons in unusual positions,” Rosnoblet shared with Watchonista. “It is a good demonstration of our work with an architectural approach: open-worked, depth, 3D in the movement, deconstruction-construction, and transparency.”
 

4. The Piccadilly Case

The Speake-Marin One&Two Openworked Flying Tourbillon comes in a new version of the brand’s Piccadilly case, which features newly designed lugs that allow the strap to be integrated closer to the case.
 

The iconic Speake-Marin crown is also set slightly further into the case to soften the overall design while keeping the original DNA.
 

5. All The Details

The Speake-Marin One&Two Openworked Flying Tourbillon comes in a choice of a 38mm or 42mm case size and available in 5N red gold or titanium. The hour and minute hands are heart-shaped and inlaid with Super-LumiNova for excellent legibility at night. The timepiece is water-resistant to 30 meters, comes on a black alligator strap with a red gold pin buckle, and is limited to 10 pieces for each version.
