Audemars Piguet Royal Oak 4100 ST with papers
The 4100ST or Royal Oak III was the first midsize model and first featuring a central seconds hand. The AP Chronicles website provides a fascinating and comprehensive history of the model of which just 2,721 units were produced in steel.
Case: The 35mm case measures approximately 44mm lug to lug and 7.2mm thick it is overall great condition with original finishing, corners, chamfers, edges, etc. throughout. Brushing is very consistent and vibrant on all surfaces and especially the bezel. There is one small surface scratch to the bezel just after 4 o’clock, that is only visible at certain angles, and not really noticeable at all on wrist.
Dial: The petite tapisserie dial is in excellent condition, featuring the early small font signature, and rich even patina across the hour markers and hands. The dial is turning slightly tropical around some of the hour markers, which is most visible in certain lighting conditions, add an additional layer of character and visual interest to and already dynamic dial that exhibits various shades of grays and blues.
Movement: The AP caliber 2123 was derived for this watch from the JLC 900 blank and went on to see numerous subsequent iterations. This particular watch is winding, setting, changing date and running well at about +/- 6s, 272-300* amplitude and 0.1ms or less beat error across all positions.
Bracelet: the original bracelet includes 21 total links, 7 of which are removable and will fit a wrist of about 7”. The bracelet is overall in great condition with no notable stretch or wear.
Includes: Original certificate of guarantee booklets, what I believe to be a service card from 2004, and leather documents folder.
