The Openworked Tourbillon Purple Hour comes to life!
In comparison to the previous models, this latest edition boasts a more modern aesthetics, with a more alluring mien and a more dynamic character, owing to the vivid purple that assumes a dominant role on the dial. This shade creates a mysterious, regal and almost mystical atmosphere, evoking unique emotions by taking on different hues when the light hits it. It is comparable to the well-known phenomenon of the “purple hour,” when the sky is filled with beautiful shades of violet, blue, purple and ultraviolet as twilight approaches. This is a breathtaking moment steeped in mystery and poetry, when light transforms and invites contemplation. This mesmerising moment is made even more magical by the harmonious dance of the flying tourbillon cage positioned at 1:30.

The combination of cutting-edge technology and unconventional aesthetics, accentuated by the daring choice of purple — a vivid colour in constant metamorphosis due to the captivating interplay of light — evokes feelings of positivity and encourages a connection with one’s inner self.
A timepiece of unparalleled elegance, the new Openworked Tourbillon Purple Hour is a lifelong companion that invites you to experience time with joy.
A TWIST OF SOPHISTICATED ELEGANCE FOR THE CASE
The Openworked Tourbillon Purple Hour is housed in the Piccadilly case, one of the brand’s recognisable signatures. It is crafted from grade 5 titanium, an alloy containing small amounts of aluminium and vanadium, which has a higher strength-to-weight ratio than grade 2 titanium and is therefore more resistant to scratching. This metal is well known for its corrosion resistance, which is almost equal to that of platinum. It is robust, extremely light, and therefore pleasant to wear. A winning combination of attributes that has captivated the discerning taste of numerous watch connoisseurs.

The purple calf leather strap with embossed denim motif, secured by a titanium folding clasp, completes the modern and eye-catching look of this creation.
REIGNS OVER THE DIAL, WHICH IS DECKED OUT IN A STRIKING SHADE OF VIBRANT PURPLE.
Beneath the anti-reflective sapphire crystal, the performance of the exquisite movement which drives the Openworked Tourbillon Purple Hour is in action.
The timepiece’s captivating dial, comprising a two-layer plate with a satin finish and a positive purple PVD coating, has been meticulously shaped to accommodate the primary mechanical components that transform this creation into a “living” entity.

The bright, shiny dial has a glossy effect on the bevelled and angled edges and a microbeaded finish on the carved pockets. As the light plays on it, it displays an array of colours, creating pleasant variations in this vivid and enigmatic shade, accentuating the exceptional craftsmanship that characterises this extraordinary piece.

The tourbillon, a fascinating and almost mysterious complication much appreciated by true connoisseurs of fine mechanical watchmaking, is undoubtedly the undisputed star of the Openworked Tourbillon Purple Hour.

Patented in 1801 by the French watchmaker Abraham-Louis Breguet, this device consists of a rotating cage in which the regulating organ — the heart of the mechanism — is placed. This complex component performs a complete rotation in one minute, neutralising the negative effects of gravity on the movement and thus improving timekeeping precision.
Speake Marin opts for the flying tourbillon instead of the traditional tourbillon. The flying tourbillon is so called because it is fixed at only one point and the construction of the entire device requires very precise work to ensure the perfect balance.
A symbol of horological excellence, the tourbillon mechanism is extremely difficult to engineer and assemble, a skill that only a few highly skilled and experienced watchmakers can master.

In addition to the hour and minute functions, which are indicated by the characteristic heart-tipped hands in homage to the brand’s English roots and are lacquered in luminescent light grey, the power reserve is positioned at 7:30. When the arrow-shaped hand points towards the bright red dot, it alerts the wearer that the 72-hour power reserve is about to run out. The combination of its technical complexity and exquisite elegance makes the Openworked Tourbillon Purple Hour a stunning example of Speake Marin’s horological vision which perfectly combine innovation with the traditional art of watchmaking.
RELIABLE AND MASTERFULLY CRAFTED
The self-winding SMA05 calibre, developed in-house by Le Cercle Des Horlogers, the Manufacture of Speake Marin powers the Openworked Tourbillon Purple Hour. It operates at a frequency of 3Hz (21,600 vibrations per hour) and provides a generous power reserve of 72 hours power from a single barrel. It is distinguished by its flying tourbillon mechanism at 1.30 o’clock: an unusual position that stands out as unique in the watchmaking panorama due to the difficulties of avoiding the time-setting module and a distinctive and recognised feature of the Maison.
As with all Speake Marin calibres, the rhodium-plated tungsten micro-rotor is integrated into the movement, thus helping to reduce its thickness and allowing the case to be of limited height.

SPEAKE-MARIN “IN-HOUSE” MOVEMENTS STRATEGY
Since
2015, Speake-Marin has initiated a movement strategy to fully develop
and assemble proprietary movements within its atelier in the Neuchatel
area, Switzerland. This new strategy gave birth to the “SMA” collection,
which includes Openworked, closed dials and Haute Horlogerie movements.
Firstly, Speake-Marin focused its efforts on Haute Horlogerie 3 Hz
movements (Minute Repeater and Double Tourbillon). Then, Speake-Marin
developed Hour Minutes Seconds 4Hz movements, which were featured in the
new One&Two design as an Openworked movement named SMA01. This
movement is particular due to the small seconds counter being positioned
at 1:30 and its integrated micro-rotor. The new SMA02 Calibre is part
of the SMA movement family and follows the Openworked collection
approach with the small seconds at 1:30. The small seconds at 1:30 meets
the Speake-Marin objective to break-away from the watchmaking codes:
Speake-Marin is the only watchmaker who positions the small seconds
there. It is actually a real constraint in terms of movement development
since the small seconds at 1:30 have to go through the time setting
module.
