MT1.1: Le Tourbillon 7 Jours Tantalum

44.00 mm tantalum case

7-day power reserve tourbillon

Openworked dial, black PVD circular satin finish and white decals

MT 7010 IRM

At the heart of the MT1.1 beats the MT 7010 IRM caliber, an open worked movement. It delivers an impressive 7-day power reserve thanks to a single oversize barrel and features a flying tourbillon positioned at 6 o’clock. The 44mm case is round. Lugless. No 3 o’clock crown. Winding from the back. A proprietary interchangeable strap system. A singular construction philosophy.

Seven-day power reserve

The construction of the MT1.1 is such that, once the tourbillon cage is positioned, the over-sized barrel occupies the maximum available space on the main plate, extending beyond its radius. One barrel. A singular construction. Seven-day power reserve achieved.

A power reserve indicator

Positioned at 12 o’clock, the power reserve indicator naturally asserts itself as both a functional and aesthetic focal point of the dial. It offers precise insight into the remaining autonomy of the movement.

A flying tourbillon at 6 o'clock

This movement features a flying tourbillon positioned at 6 o’clock, oscillating at a frequency of 3 Hz. It is the frequency that guarantees stability, precision and long-term chronometry without over-stressing the system. Controlled energy. Controlled amplitude.

A lugless watch without crown at 3 o'clock

Form Follows the Movement. Style is refined to the purest essentials in a minimalist language designed to serve what matters. A round case, no angles, pure ergonomics and domed sapphire offering the widest possible view of the caliber. Thoughtful in construction. Instantly recognizable. A watch built from the inside out.

A back winding system and a selector

Everything moves to the back for symmetry, efficiency and speed. Winding is done from the crown placed at the rear, faster and more direct than a traditional side crown. A pusher on the case side at 3 o’clock replaces the classic pull-out crown system. One press engages time-setting mode. The movement is disconnected and the hands can be adjusted. Another press returns the watch to winding mode and re-engages the movement. It’s the same logic as pulling and pushing a crown, but simplified into a single, controlled action.

Openworked front and closed back

The front is fully open. The movement explains itself instantly. The mechanics revealed with intent. An openworked movement designed that way from the start. Legible, functional, aesthetical. Light, geometry and finishing reveal functions. Every component is hand-finished. The back is the opposite. An architecture closed by design, defined by intent. A single transversal bridge gives space to a pure canvas for Marco Tedeschi’s signature decoration: concentric geometries, circular patterns, flowing in repetition. A Zen aesthetic, engineered with precision.

A proprietary interchangeable strap system

The strap is integrated into the case architecture and released via pushers on the case back. It keeps the design clean, uninterrupted and fully integrated into the case pure roundness geometry. Function is hidden. Aesthetic is preserved. No visible complexity on the dial side. No unnecessary hardware. One press. One release.

Form follows the movement

Marco Tedeschi’s construction philosophy is guided by a simple principle: Refining everything to the purest essentials in a minimalist language designed to serve what matters. Performance is never pursued at the expense of precision; the two must exist in perfect balance, serving only what is useful and meaningful to the movement itself. No extravagance, no record-seeking. Only the right solution, exactly where it is needed. Marco also reduces complexity wherever possible. Fewer components mean fewer points of failure. Efficiency by design. Aesthetic is never imposed but emerge from it naturally: Form Follows the Movement.
