imepieces crafted by L.Leroy, the esteemed Maison that was established in Paris in 1785 by Charles Leroy, have spanned the centuries, bestowing their owners with unparalleled elegance and distinction. In 2025, the year of its 240th anniversary, L. Leroy is back in the world of Haute Horlogerie.

The case of the Osmior Bal du Temps is crafted from noble metals such as 18k 5N red gold and platinum, as well as a more modern material, grade 5 titanium, which is highly appreciated for its lightness. These three variants have a diameter of 43mm and a height of 13.6mm (including the domed sapphire crystal). With a polished surface and a “tambour” shape, a signature feature that immediately identifies the Osmior collection, the models are distinguished by a flat, recessed case middle in relation to the bezel and the case back.

An intriguing detail immediately commands attention: the display features a single hand, that of the hour, while the minutes are indicated by the minute repeater. A time reading that is not totally new for the Maison, which is inspired by the historic “à tact” watch made for Prince Emil Maximilian Leopold August of Hesse around 1810 and which has already been the subject of a recent timepiece produced by the brand.

The lugs are chamfered and slightly flared, with rounded ends. The crown is engraved with the polished, interlaced double ’L’ of the Maison’s logo, which stands out against the sandblasted surface. Grooved notches around the circumference facilitate grip when winding the watch and setting the time.

The openworked dial is a veritable hymn to micro-mechanics, showcasing the intricate mechanics of hand-wound calibre L601SQ, equipped with the prestigious minute repeater and flying tourbillon, the latter visible at 6 o’clock. Only highly qualified watchmakers can design and assemble these two complications to perfection, resulting in perfectly harmonious sounds and excellent chronometric precision.
