Perfect harmony is an unending quest. At Richard Mille, it’s also a matter of fusion. As with a case and its calibre.

Some 600 parts which, once assembled, constitute the most complex of all the brand’s automatic movements: the calibre RMAC4, which supplies the RM 65-01 Split-Seconds Chronograph with its formidably precise chronometric information.

And, right in time for summer, the existing RM 65-01 collection (red gold and Carbon TPT®, titanium, Carbon TPT®, and grey Quartz TPT®) is enriched with more vivid shades. Richard Mille continues to exhibit its disruptive personality with two new versions. These evoke, respectively, azure skies and the fiery celestial orb. The first, possessing a case crafted of pastel blue Quartz TPT® will join the collection. The latter, issued in a limited edition of 120 watches, features a dark yellow Quartz TPT® whose brightness warms the pageantry of gears visible through its skeletonised dial.

The dominant colours of the dial contribute to establishing a rich chromatic palette brimming with energy. Each colour is associated with a function on the dial, thereby enhancing ease of reading, a colour code that is shared with the pushers and crown.

Equipped with a six-column wheel, the calibre RMAC4 masterfully orchestrates the measurement of time. This automatic movement possesses a high-frequency balance with variable inertia, oscillating at 36,000 vibrations per hour (vph). A pusher located at 8 o’clock makes it possible to rapidly recharge the spring of its fast-rotating barrel. The motor of this chronograph then benefits from a 60-hour power reserve. The function selector on the crown enables the wearer to switch quickly from traditional winding mode (W) to setting the semi-instantaneous date (D), or the hours and minutes (H).

The RM 65-01 Automatic Split-Seconds Chronograph in dark yellow Quartz TPT® and pastel blue Quartz TPT® promise a summer brimming with sensations and experiences.
