Marco Tedeschi Puts a Floating Central Tourbillon Under Black Aventurine

Marco Tedeschi’s Central Floating Tourbillon has always been less about decoration than architecture.

Its latest version gives that construction a darker, more celestial frame, pairing the raised central tourbillon with a black aventurine dial and a satin-finished Grade 5 titanium case.

The result is a watch that feels highly technical without losing the visual theatre expected from independent high watchmaking.

At a glance

A movement that starts at the centre

The Central Floating Tourbillon is one of Tedeschi’s defining ideas, with roots stretching back to 2006 when he was still a student.

The initial aim wasn’t simply to make a tourbillon.

Tedeschi was exploring how to create a manually wound movement with a meaningful power reserve from a single barrel, and that line of thought led him to place a large barrel on the central axis.

Once the barrel sat at the centre, the regulating organ followed the same logic.

That progression eventually became the patented floating central tourbillon, raised above the movement so it appears visually detached from the mechanics underneath.

It’s a different hierarchy from the usual tourbillon watch, where the regulating organ is often treated as a dial-side aperture or a peripheral flourish.

Here, the case, time display and winding system all seem to orbit the calibre’s central premise.

Black aventurine in a titanium case

The Black Aventurine edition is housed in a 45mm Grade 5 titanium case measuring 20mm thick, or 12.5mm without the domed sapphire crystal.

The case is fully round, satin-finished and free of conventional lugs, which helps preserve the almost instrument-like symmetry of the design.

Instead of placing a crown on the side of the case, Tedeschi uses a D-ring crown on the caseback for winding and setting.

A flush function-switch push button sits at 3 o’clock, keeping the profile clean while still allowing the wearer to operate the watch.

The dial is built in three layers of black aventurine glass, giving the watch a restrained sparkle rather than a loud decorative effect.

The outer ring carries the white minute track and is fixed to the case, while the intermediate dial is mounted to the fixed hour wheel and the innermost section attaches to the movement mainplate.

An opening at 9 o’clock reveals part of the gear train, adding a mechanical counterpoint to the otherwise cosmic surface of the aventurine.

Time display around the floating tourbillon

Reading the watch is deliberately peripheral.

Rhodium-plated hands with white Super-LumiNova indicate the hours and minutes around the edge, leaving the central construction unobstructed.

The display is driven by a planetary gear system mounted on ceramic ball bearings, allowing the time indication to move around the central mechanism rather than crossing over it.

Inside is the manually wound KS 7’005 calibre, a 220-component movement with 27 jewels and a frequency of 21,600 vibrations per hour.

Its oversized central barrel delivers a five-day power reserve, which is the practical reason this architecture exists in the first place.

The tourbillon, balance and barrel share the central axis, turning the movement layout into the watch’s main visual signature.

Details & Specifications

For collectors drawn to independent watchmaking, the appeal is clear.

This isn’t a conventional tourbillon dressed in a striking dial, but a watch where the movement’s unusual construction dictates almost every visible decision.

In black aventurine, the Central Floating Tourbillon gains a quieter, more nocturnal character while keeping the technical clarity that makes Tedeschi’s work stand apart.
