Hailey Bieber has quietly curated one of the most beautiful collections of mini luxury watches in the celebrity style landscape. Known for her refined, minimalist aesthetic, she gravitates toward ultra-elegant vintage timepieces that perfectly complement her signature polished look.
Since being announced this year as an official Audemars Piguet brand ambassador, we can expect to see her wearing even more pieces from the brand. However, Hailey’s personal watch collection extends far beyond her AP partnership. She owns some of the most stunning mini vintage watches from Piaget, Audemars Piguet, and Patek Philippe—pieces that reveal her deep appreciation for rare, jewellery-inspired designs from the 1970s through the early 2000s.
Her collection also underscores a rising trend in the luxury watch world: the return of the “mini watch.” These smaller, jewellery-forward designs are becoming increasingly coveted among women who prefer refined, feminine silhouettes over oversized sports watches. Hailey Bieber’s choices not only mirror this shift but have helped fuel the growing interest in dainty watches across social media and the secondary market.
Below are the watches I was able to identify, with prices accurate at the time of publishing but always subject to change.
Royal Oak Lady
Audemars Piguet
The Royal Oak line is one of Audemars Piguet's most iconic designs, originally created by Gérald Genta in the early 1970s. The ladies' Royal Oak was introduced in 1976, led by designer Jacqueline Dimier with the debut of reference 8638. This 25 mm vintage "Lady" model is an exceptionally scarce find today. Interest in smaller vintage Lady Royal Oak pieces has surged further following the recent launch of the new Mini Royal Oak in frosted gold.
pre-owned ~£20,000+
Tesoro
Tiffany & Co
A charming treasure from the 1990s, this Tiffany & Co. Tesoro watch hails from an era when the house's timepieces were at the height of desirability. Crafted in 18-carat yellow gold and set with diamonds, this petite and exquisitely detailed jewel is no longer produced and can now only be found through select resale platforms.
pre-owned ~£12,000+
Day-Date 36
Rolex
Nothing stands out more for me than the combination of a turquoise dial and yellow gold. This Rolex Oyster Perpetual Day-Date 36 comes in yellow gold with diamonds on the bezel, featuring both the day and the date display. The beautiful, veined natural-stone turquoise dial is exclusively reserved for gold or platinum versions of the Day-Date 36. Extremely hard to obtain at retail, its resale value is only increasing.
£57,650
Polo
Piaget
A dazzling creation from the 1990s, this vintage Piaget Polo is a masterpiece of luxury and craftsmanship. Fully pavé-set with approximately 20 carats of fine white brilliant-cut diamonds and crafted in 18k yellow gold, it features an integrated flexible bracelet and a quartz movement. Its astonishing sparkle gives it a truly jewellery-like presence, blurring the line between high watchmaking and high jewellery.
pre-owned ~£20,000
Mini Royal Oak frosted gold
Audemars Piguet
This year she became an Audemars Piguet brand ambassador, and of course she's wearing one of the most sought-after mini watches of the moment: the Audemars Piguet Mini Royal Oak in frosted gold. Nearly impossible to obtain at retail, these pieces appear only through resellers at significantly escalated prices. Inspired by the 1997 Mini Oak, this contemporary 23 mm interpretation features an 18-carat yellow gold case and bracelet finished in shimmering Frosted Gold, paired with a tone-on-tone Petite Tapisserie dial. It is powered by the quartz Calibre 2730.

Polo
Piaget
A rare and exquisite find, this dainty vintage Piaget Polo features a refined 19mm dial. First introduced in the 1980s, the Piaget Polo collection — described by Yves Piaget as a watch for those who appreciate both luxury and sport — quickly became an icon of elegant casual refinement. Crafted in 18-carat yellow gold and adorned with diamonds, this miniature ladies' model is exceptionally scarce and today can only be sourced through select vintage resellers.
pre-owned ~£10,000+
Nautilus
Patek Philippe
Probably one of the most worn in her collection is this beautiful mini Patek Philippe Nautilus Ladies Ref. 4700, a vintage quartz-powered luxury sports watch produced between 1981 and 2004. It is highly regarded for its iconic Gérald Genta–designed case, and this particular example is one of my favourites — especially because her model features a tapisserie dial.
~£20,000
