Richard Mille Unworn 2023 RM 67-01 Extra Flat

The standout feature of the RM 67-01 is its ultra-thin profile. At just 7.75mm thick, it’s one of the slimmest watches in Richard Mille’s collection, offering a sleek and refined alternative to the brand’s typically bold and rugged designs—perfect for everyday luxury and discreet elegance.

The RM 67-01 is powered by the automatic Caliber CRMA6, a skeletonized movement developed in-house. It combines aesthetic transparency with durability and precision, offering a 50-hour power reserve and a slim structure that doesn’t compromise on performance.

While it has a refined silhouette suitable for formal wear, the RM 67-01 still embodies Richard Mille’s sporty DNA. Its tonneau-shaped case, exposed movement, and high-tech materials like grade 5 titanium give it a dynamic edge, making it versatile for both luxury and casual environments.

The RM 67-01 is typically crafted from lightweight yet durable materials such as titanium, Carbon TPT®, or gold, depending on the variant. These materials offer both aesthetic appeal and practicality, ensuring the watch remains comfortable and resistant to wear over time.

This model is ideal for those who appreciate Richard Mille’s engineering excellence but prefer a slimmer, more understated profile. It appeals to collectors and professionals who want a technically advanced watch that fits comfortably under a cuff while still making a subtle statement.
