If you’re looking for a timepiece that seamlessly merges jewelry and watchmaking, the Cartier Baignoire de Cartier Size 15 might be the perfect choice. Here are four standout features of this elegant watch:
Cartier Baignoire Mini Size 15 Looks More Like Jewelry Than a Watch
Cartier is known for iconic jewelry pieces like the Love Bracelet, and they’ve channeled that expertise into the Baignoire. At a glance, it resembles a sleek gold bangle rather than a typical watch. Its slim, oval-shaped case and seamless closure give it the feel of fine jewelry—ideal for anyone who wants a functional timepiece that doubles as a statement accessory.
It’s Remarkably Small and Thin
The Baignoire Size 15 measures about 24.6 mm tall, 18.7 mm wide, and only 7 mm thick. Many traditional women’s watches start at around 28 mm, so this one is noticeably more petite. Its slender profile makes it incredibly comfortable on the wrist and enhances its resemblance to a graceful bracelet.

Classic Cartier Dial Details
Even though it’s compact, the watch’s face proudly showcases Cartier’s trademark design elements. The white (or “silvered”) dial features Roman numerals, lending it a timeless look. You’ll also notice Cartier’s signature blue steel sword hands, which keep the dial clean and uncluttered—there’s no second hand to distract from its minimalist elegance.
Quartz Movement for Ease and Affordability
A key advantage of this model is its quartz movement, which helps keep the case ultra-thin and the maintenance simple. Unlike automatic watches that require regular servicing, a quartz watch only needs a battery change every few years. It’s a practical choice that also keeps the cost more accessible than many mechanical alternatives.

Is this watch for you?
If you’re after a refined, jewel-like watch that retains Cartier’s classic allure, the Baignoire de Cartier Size 15 (reference WGBA0018) is an outstanding choice. It wears like a piece of art, offers modern convenience with its quartz movement, and features timeless details like Roman numerals and a delicate gold bracelet. It’s a luxurious yet practical statement piece for any occasion.
