Inserted 03/05/2023
The Richard Mille RM 59-01 case is molded from a polymer matrix injected with carbon nanotubes — a material derived from aerospace research that yields extraordinary rigidity at virtually negligible weight, making it one of the most technically exotic watch cases ever produced. Only 50 examples were made, each carrying a retail price of $620,000. The Crown Prince of Brunei, Haji Al-Muhtadee Billah, one of Asia's most prominent royal watch collectors, was recently spotted wearing precisely this piece on his wrist.

Inserted 29/04/2023
The Richard Mille RM 055 Bubba Watson is one of the most technically demanding skeletonized sports watches in the brand's catalog — its grade 5 titanium case and ATZ ceramic bezel bring total weight down to near-nothing on the wrist, a counterintuitive feat for a watch commanding six-figure prices. Crown Prince Haji Al-Muhtadee Billah of Brunei, heir apparent to one of Southeast Asia's wealthiest royal dynasties, was recently spotted wearing this ultra-light tourbillon alternative, a choice that signals connoisseurship well beyond purely decorative horology.

The Richard Mille RM 38-01 houses one of the most mechanically singular complications in modern watchmaking: a tourbillon paired with a patented g-force sensor originally conceived to measure the impact forces generated during a golf swing — calibrated specifically around Bubba Watson's legendary drives. Only 50 examples were ever produced, each carrying an $825,000 list price. Crown Prince Haji Al-Muhtadee Billah of Brunei, one of the world's most serious royal watch collectors, was recently spotted with this rare piece firmly on wrist.
Crown Prince of Brunei Haji Al-Muhtadee Billah Spotted Wearing Titanium Avantist Martina Navratilova Wimbledon 1990 Legend Series
Inserted 30/11/2022
Limited to just 30 pieces worldwide, the Avantist Martina Navratilova Wimbledon 1990 Legend Series is one of the most exclusive Swiss-made sports commemoratives in existence — making it a genuine collector's artifact rather than a marketing exercise. The tonneau-shaped titanium case, deep navy dial, and rubber strap visible on the Crown Prince's wrist at his birthday celebration align precisely with the known specification of this ultra-rare release, underscoring that Brunei's royal family continues to favour distinguished, low-production horology over mainstream luxury.
Crown Prince of Brunei Haji Al-Muhtadee Billah Spotted Wearing Richard Mille RM35-01
Inserted 30/11/2022
The Richard Mille RM35-01 is built around a grade 5 titanium baseplate and uses a skeletonized manual-winding caliber RMUL1, originally developed in collaboration with Rafael Nadal — making it one of the brand's most technically accomplished sport references. Constructed with a Carbon TPT case, it weighs barely 33 grams on the wrist, a feat that borders on engineering absurdity. Crown Prince of Brunei Haji Al-Muhtadee Billah, heir apparent to one of the world's wealthiest absolute monarchies, was spotted wearing this lightweight titan.
