Additional Informations: The Royal Oak reference 4100 ST by Audemars Piguet dates from the 1980s and is part of the early automatic Royal Oak models with date display. It features the characteristic two piece stainless steel case of this reference, paired with the integrated steel bracelet that defines the original Royal Oak design.
A key highlight of this example is the original so called tropical dial, which has developed an even and warm brown tone over time. The tapisserie pattern remains clearly defined and fully intact. Dial printing, applied hour markers and the date window appear sharp, well balanced and in excellent condition.
The case and bracelet were professionally refinished as part of a recent full service. The signature brushed surfaces and polished bevels of the Royal Oak are cleanly executed and geometrically correct. The edges are crisp and well defined. Screws, bezel and overall case shape correspond to the original appearance of this reference.
Thanks to the complete service, the watch is in excellent technical condition. It is offered without original box or delivery papers.
Overall, this is an authentic Royal Oak 4100 ST featuring a collector relevant tropical dial, high quality refinishing and a well documented and coherent overall condition, as visible in the accompanying images.
