About this product
White mother-of-pearl with diamond markers under a flat diamond-set yellow gold bezel — the more assertive setting, where 278343RBR uses a domed profile. Natural shell inside a hard ring of stones, no two dials alike. On the five-link Jubilee in 31mm Yellow Rolesor. Calibre 2236 drives it at roughly fifty-five hours, sealed to 100 metres.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
