The reference 4100 with its 35 mm case has all the characteristics from the iconic 5402: a tonneau-shaped steel case with lapidated lugs, four screws in the bands to secure the removable steel bracelet, an octagonal steel bezel secured by eight screws and a plain steel screwed case back. The lot here offered is in a very well-preserved original overall condition, featuring the iconic characteristics a Royal Oak must have: the serial number on the inner case cack indicates that this watch is a B-series, and with this reference it dates to 1978. Engraved on the back is number 570, suggesting it was the five hounded and seventies made in this configuration. The watch, furthermore, still has the original, hexagonal non-marked winding crown. Under the flat sapphire crystal glass, a superb anthracite, lovely patinated, tapissserie gray dial with a light topicalization that is spreading all around, applied luminous baton indexes, gold luminous hands, an aperture for the date at 3, an outer minute division. Famous icon and aesthetically appealing, this watch also comes with the extract from the archives confirming caliber 2123.
