Inserted 05/06/2023
The Patek Philippe Nautilus 5711/1A-010 was discontinued in 2021 after a final limited run featuring a special olive-green dial, instantly making it one of the most sought-after references in modern watchmaking history. The standard steel 5711/1A-010 with its iconic blue sunburst dial remains the benchmark grey-market trophy piece, commanding multiples of its retail price. Sultan Hassanal Bolkiah of Brunei — one of the world's wealthiest individuals and a legendary watch collector — was spotted wearing this horological icon, a modest choice by his extraordinary standards.
Sultan of Brunei Hassanal Bolkiah Spotted Wearing Richard Mille RM 27-01 Tourbillon
Inserted 03/05/2023
The Richard Mille RM 27-01 houses a tourbillon movement weighing a staggering 3.5 grams in its entirety — a feat of miniaturized engineering that pushed the boundaries of what was considered possible in mechanical watchmaking when it debuted in 2013. Developed in close collaboration with tennis legend Rafael Nadal, the RM 27-01 was built to withstand the violent shock forces generated during a professional tennis serve. Sultan Hassanal Bolkiah of Brunei, one of the world's most prolific watch collectors, was spotted wearing one of only 50 examples ever made.
Sultan Hassanal Bolkiah Spotted Wearing Richard Mille RM 67-02 'Alex Zverev'
Inserted 30/04/2023
At just 32 grams, the Richard Mille RM 67-02 is the lightest automatic watch the brand has ever produced — a feat of engineering that places it firmly at the intersection of haute horlogerie and aerospace-grade materials science. The skeletonized case combines grade 5 titanium and Carbon TPT, achieving a profile that sits almost imperceptibly on the wrist. Spotted wearing this technically audacious timepiece is none other than Hassanal Bolkiah, Sultan of Brunei — one of the world's most storied royal watch collectors.
Sultan Hassanal Bolkiah of Brunei Spotted Wearing Titanium Richard Mille RM 011 Felipe Massa Flyback Chronograph
Inserted 30/04/2023
The RM 011 was Richard Mille's first flyback chronograph and remains one of the brand's most technically accomplished references, housing the calibre RMAC1 with a column wheel, annual calendar, and flyback function in a case that weighs almost nothing thanks to its Grade 5 titanium construction. That a reigning sultan — one of the wealthiest individuals on earth and a legendary collector of extreme horology — chooses the RM011-FM over something far rarer in his own arsenal speaks to how seriously the market respects this reference.
Sultan of Brunei Hassanal Bolkiah Spotted Wearing Richard Mille RM 003-V2 Tourbillon Dual Time Zone
Inserted 29/04/2023
The Richard Mille RM 003-V2 pairs a carbon nanofibre baseplate with a microblasted black titanium case — a construction so technically demanding it places the piece among the most architecturally complex wristwatches ever produced. The manually wound tourbillon movement manages dual time zone display within a skeletonised architecture that keeps weight to an absolute minimum. Sultan Hassanal Bolkiah of Brunei, one of the world's wealthiest heads of state and a legendary collector, was spotted wearing this six-figure complication with characteristic understatement.

Inserted 02/12/2022
A true 1/1 commission from one of the world's wealthiest monarchs: the Richard Mille RM 002 Military Edition tourbillon built for Sultan Hassanal Bolkiah of Brunei stands apart from standard production through oversized hour markers engineered for legibility under field conditions. The RM 002 was Richard Mille's second-ever reference, establishing the brand's signature skeletonized tonneau architecture and multi-information tourbillon layout. That this piece exists as a singular titanium bespoke commission tells you everything about the Sultan's standing as a serious — and extraordinarily resourced — horological patron.
Sultan of Brunei Hassanal Bolkiah Spotted Wearing Bespoke Richard Mille RM035 Rafael Nadal in Magnesium-Aluminum Alloy
Inserted 01/12/2022
The Richard Mille RM035 was originally engineered in partnership with Rafael Nadal to survive the punishment of professional tennis — yet the Sultan of Brunei commissioned a one-of-a-kind variant with enlarged luminous hour markers, a modification significant enough to alter the dial architecture of one of watchmaking's most technically sophisticated cases. Hassanal Bolkiah, whose personal watch collection is among the most extravagant on the planet, was photographed wearing the piece during his public address urging Bruneians to observe COVID-19 safety protocols, offering a rare close-up of this extraordinary bespoke commission.
Sultan of Brunei Hassanal Bolkiah Spotted Wearing Richard Mille RM56-01 Tourbillon Sapphire
Inserted 30/11/2022
The Richard Mille RM56-01 Tourbillon Sapphire is one of the most technically audacious watches ever produced: its entire case — top, bottom, and middle — is machined from a single block of synthetic sapphire crystal, making it virtually invisible on the wrist and limited to just five examples worldwide. Retail price sits north of £1.14 million. The man wearing it, Sultan Hassanal Bolkiah of Brunei, is widely regarded as one of the most serious watch collectors on the planet — a figure whose wrist has served as a showcase for horology's absolute apex for decades.
Sultan of Brunei Hassanal Bolkiah Spotted Wearing Richard Mille RM67-01 in White Gold
Inserted 30/11/2022
At just 7.75mm thick, the Richard Mille RM67-01 holds the distinction of being the flattest watch the Swiss-Caribbean manufacture has ever produced — a remarkable feat for a brand whose tonneau-cased, skeletonized pieces are typically far bulkier. Powered by the in-house automatic caliber CRMA6 with a variable geometry rotor, the RM67-01 in white gold represents the quieter, more refined side of Richard Mille's portfolio. Sultan Hassanal Bolkiah of Brunei, one of the world's wealthiest individuals and a legendary watch collector, wore the piece in keeping with his reputation for understated horological sophistication.
Hassanal Bolkiah Spotted Wearing His Piece Unique Pink Sapphire Richard Mille RM56-02
Inserted 30/11/2022
The Richard Mille RM56-02 Piece Unique in pink sapphire represents perhaps the most technically audacious case construction in modern watchmaking — a monocoque sapphire crystal shell machined to just millimeters of thickness, housing a suspended tourbillon movement held by cables rather than a traditional baseplate. As a one-of-a-kind commission, the pink sapphire variant exists entirely outside the standard RM56-02 production run, placing it in a category of wristwear that money alone cannot easily acquire. Few wrists in the world are more fitting than that of Hassanal Bolkiah, Sultan of Brunei.

Inserted 30/11/2022
The Patek Philippe Aquanaut 5168G is one of the brand's most quietly subversive references — a white gold sports watch paired with a tropical khaki green dial that Patek introduced to widen the Aquanaut's palette beyond its classic ebony roots. Launched in 2018, the 5168G runs the in-house Caliber 324 S C and sits at 42.2mm, making it the largest expression of the line. Sultan Hassanal Bolkiah — one of the world's most storied royal watch collectors — was spotted on the wrist of a man whose personal collection is the stuff of horological legend.

The green ceramic Cerachrom bezel — earning the watch its 'New Kermit' nickname — has already become one of the most recognisable references in modern Rolex production. Sultan Hassanal Bolkiah, one of the world's wealthiest heads of state and a legendary collector of timepieces, was spotted wearing this modern sports classic.

Inserted 30/11/2022
The Patek Philippe Nautilus 5711/1A-014 is arguably the most consequential watch release of the 2020s — a deliberately final chapter for the iconic ref. 5711/1A, announced simultaneously with its discontinuation in January 2021. Patek produced it in limited but undisclosed quantities, fitted with a sunburst olive-green dial never seen before on the Nautilus line. That a reigning monarch of Sultan Hassanal Bolkiah's stature chose to wear it publicly — over countless bespoke complications in his legendary collection — speaks volumes about the reference's cultural weight.

Inserted 30/11/2022

Sultan of Brunei Hassanal Bolkiah, one of the world's wealthiest heads of state and a legendary collector with a private museum's worth of horological treasures, was spotted wearing this white gold masterpiece — a choice that, even by royal standards, signals serious connoisseurship.
