Blancpain Lady B Revives the Ladybird as a Tiny Mechanical Jewel

Blancpain’s newest women’s watch is small in size but pointed in intent.

The Lady B brings the maison’s mid-century Ladybird idea into the present as a spherical, wrist-worn jewel that remains fully mechanical, a fitting move from a brand long defined by its refusal to make quartz watches.

It also brings Betty Fiechter back into the spotlight, the executive whose leadership helped shape Blancpain at a time when women rarely held such positions in Swiss watchmaking.

At a glance

Betty Fiechter’s Ladybird returns in miniature

The Lady B takes its name from Betty Fiechter, a central figure in Blancpain’s history and one of the rare women leading a Swiss watch company in the middle of the 20th century.

Its closest historical touchpoint is the Ladybird, introduced in the 1950s and celebrated at the time for its extremely small round case.

The period Ladybird measured just 11.85mm in diameter and was positioned as a technical feat as much as an elegant accessory.

Blancpain’s new interpretation doesn’t try to reproduce that watch outright.

Instead, it borrows the spirit of the Bullet version, whose strap passed through an opening in the back of the case, making quick changes part of the design rather than an afterthought.

A spherical case with no visible lugs

The Lady B measures 19mm across and 13.20mm thick, with a rounded case profile that gives it the character of a small polished object rather than a conventional miniature wristwatch.

Its two-part case construction keeps the back discreet on the wrist, helping the watch read as a compact jewel from most angles.

There are no lugs, which is essential to the design.

The 10mm double-tour calf leather strap passes directly through a machined opening in the caseback, allowing the strap to be swapped quickly and keeping the silhouette clean.

Blancpain offers the strap in seven colours including white, beige, mocha, burgundy, blue, coral and purple.

The dial is deliberately restrained, with an opaline finish and applied polished stick markers.

On the red gold model, the hands and markers are in red gold, while the stainless-steel version uses grey gold details for a cooler tone.

Calibre 615 keeps the Lady B firmly mechanical

The technical interest sits beneath that jewellery-like exterior.

Inside is Blancpain’s automatic Calibre 615, a small round manufacture movement measuring 15.70mm by 3.90mm.

The movement was introduced in 1995 and has been refined over time, including the addition of a silicon balance spring.

It runs at 21,600 vibrations per hour and is built from 180 components, including 29 jewels.

The display is kept to hours and minutes, which suits the watch’s scale and keeps the dial free of clutter.

Details & Specifications

The Lady B is at its best when viewed as more than a dainty anniversary piece.

It’s a reminder that miniature mechanical watchmaking has its own discipline, and that Blancpain’s history with women’s watches is not a side note but a meaningful part of the brand’s identity.
