Description: Audemars’ ‘medium-sized’ offering of their Royal Oak – a 35mm case, which wears closer to a 39mm, whose brutalist design made stunning by gold. Whose limited production, only 88 ‘BA’ 4100s were produced in 1977, and automatic movement, a modified LeCoultre 900, makes for a very elusive piece. The gold of this watch has been made glossy by time and wear and is unpolished, whose almost-tropical grey petite tapisserie dial reveals brassy tones.

Case: 35mm unpolished 18k yellow gold

Bezel: Unpolished 18k yellow gold, gold screws remain undisturbed

Dial: Brass, grey petite tapisserie Stern-made with 18k yellow gold hands, indices, and date wheel

Bracelet: 477 H-link, unpolished 18k yellow gold
