Product Overview

The BBA Factory Richard Mille RM 07 combines a factory-stated 31.4mm steel case with a black dial and decorative stone detailing.

The stone-set bezel frames the dial, while central hour and minute hands provide a simple time display. In addition, the contrast between the black dial and sparkling accents gives the watch a jewellery-inspired appearance.

According to the supplied specifications, this version uses a CRMA2-style automatic mechanical movement. A natural rubber strap and stone-set folding clasp complete the design.

Movement and Functions

The factory lists a CRMA2-style automatic mechanical movement for this version. Its functions include central hours and minutes.

The automatic winding system uses wrist movement to build stored energy. However, the supplied information does not confirm the movement’s internal construction or power reserve.

Central Hour Hand

The shorter central hand displays the current hour.

Together with the minute hand, it provides the watch’s main time display.

Central Minute Hand

The longer central hand indicates the current minutes.

Because the supplied specifications list only hours and minutes, this page does not include a seconds display, date or chronograph function.

Case and Bezel

The steel case measures 31.4mm according to the factory information. However, the factory has not clarified whether this measurement represents case width or another dimension.

Small decorative stones cover the bezel and frame the black dial. Meanwhile, their reflective appearance adds contrast to the steel case.

The factory describes these stones as diamonds, but it has not supplied their identity or certification. Therefore, this page uses stone-set wording without claiming natural or laboratory-grown diamonds.

Dial and Crystal

The black dial includes decorative stone detailing and central hour and minute hands.

Its dark background contrasts with the surrounding stones. In addition, the simple two-hand layout keeps the time display straightforward.

A sapphire crystal covers the dial. Its anti-reflective coating helps reduce glare under different lighting conditions.

Strap and Clasp

The natural rubber strap adds flexibility and a sporty element to the design. Meanwhile, the stone-set folding clasp continues the decorative theme of the bezel and dial.

Close the clasp fully before wearing the watch. Also, avoid exposing the rubber strap to solvents, perfume or harsh cleaning products.

Water Resistance

The factory states 50 metres of water resistance. However, no independent pressure-test report confirms this rating for the individual watch.

Avoid swimming, showering and immersion until a professional test establishes its water resistance. In addition, keep the crown secured and do not adjust it while the watch is wet.

Care Instructions
Clean the case and dial surroundings gently with a soft microfibre cloth.
Avoid impacts that could damage the stone settings.
Keep the watch away from strong magnetic fields.
Do not use abrasive cleaners or solvents.
Check the clasp before wearing the watch.
Arrange an inspection if a stone appears loose or the movement behaves unusually.
Frequently Asked Questions
What size is the watch?

The factory lists 31.4mm. However, it has not supplied the full case dimensions or identified the measurement axis.

What movement does this version use?

The supplied specifications describe a CRMA2-style automatic mechanical movement with central hours and minutes.

Are the decorative stones genuine diamonds?

The factory calls them diamonds, but their material and origin remain unverified. Therefore, this page describes them as decorative stones.

Does the watch have a seconds hand?

The supplied specifications list only central hour and minute hands.

What colour is the dial?

The dial is black with decorative stone detailing.

What type of strap does it use?

The factory specifies a natural rubber strap with a stone-set folding clasp.

Can I wear the watch while swimming?

Swimming is not recommended without an individual pressure test. The factory-stated 50-metre rating alone does not establish actual water resistance.

Will you inspect the watch before shipment?

Yes. Our team will inspect the movement, exterior, visible stone settings and clasp after the watch arrives from the factory.

We will then provide two QC videos showing movement operation and the actual watch. Finally, we will confirm the model and delivery details before shipment.
