This 40 mm 18 ct yellow gold timepiece features a monobloc Oyster case, a screw-down crown, and 100-meter water resistance. Reference 228238-0007 includes a fluted bezel, a sapphire crystal with a Cyclops lens, and a black dial with Chromalight-filled markers. Driven by the self-winding calibre 3255, it offers a 70-hour power reserve, Superlative Chronometer certification, and a President bracelet with a concealed Crownclasp.
