Audemars Piguet used the Royal Oak Offshore’s thirtieth anniversary to expand the smaller 37 mm side of the collection. The 2023 group combined four self-winding chronographs with a black ceramic Music Edition, proving that a reduced diameter did not require a restrained design. Gem-set bezels, vivid dials and interchangeable rubber straps gave the chronographs a jewellery-led character, while the Music Edition used an equaliser-inspired dial and dark ceramic case. The useful comparison is therefore not simply size; it is how the Offshore’s layered architecture changes across materials and functions.

Four colourful chronographs
The chronograph group included steel, pink-gold and yellow-gold cases with bezels set in diamonds or coloured gemstones. Their dials use the compact Lady Tapisserie pattern, applied markers and a three-register layout with the date positioned between four and five. Although the visual emphasis is colour, the underlying geometry remains precise: the octagonal bezel, eight exposed screws, pusher guards and short integrated strap connection must all stay in proportion. On gem-set interpretations, uniform stone height and clean alignment are as important as colour saturation.

The black ceramic Music Edition
The 37 mm Music Edition takes a different route. Its black ceramic case is paired with titanium details and a dial built from coloured vertical bars that recall an audio equaliser. The display is time only, so the face has more open space than the chronographs. A mosaic-pattern rubber strap continues the music theme. Because the case is nearly monochrome, weak edges and inconsistent surface finishing become more visible. The octagonal bezel should remain sharply defined even when the material absorbs much of the light.

Movement layouts must match
The chronographs and the Music Edition do not share one interchangeable display. Chronograph references require working registers with the correct scale and hand behaviour, while the time-only edition needs a movement and dial without decorative, non-functional counters. Compare the case-back view, rotor position and balance location with the exact reference. A visually busy dial can hide functional shortcuts, so operate the crown and pushers and observe what each hand actually does.
How 37 mm wears
Diameter does not tell the complete story because the Offshore has a broad bezel, projecting crown protection and a thick multi-part case. A 37 mm reference can still feel substantial, especially when bright gemstones extend the visual boundary. The integrated rubber strap drops quickly from the case, which can help on a smaller wrist. Check the gap at each strap end, the quick-change release and the folding clasp or pin buckle specified for the edition. Those practical parts should work cleanly rather than merely resemble the original.
What to compare first
Begin with the reference number, case material and dial type. Then compare bezel setting, screw position, dial pattern, register spacing and strap combination in that order. Do not use a photograph of the steel diamond model to judge a yellow-gold sapphire version. Audemars Piguet made each configuration intentionally distinct, and mixing their details is a more revealing error than a minor colour shift caused by lighting.
