The present watch is a previously unrecorded example of a Rolex wristwatch featuring both centre and subsidiary second hands. Such contradictory mechanism is predominantly known to have been made by Omega in the mid 1940s (see Armbanduhren - 100 Jahre Entwicklungsgeschichte by Kahlert, Mühe, Brunner, third edition, p. 344, pl. 599 a & b) for a small series of watches which were never commercialized. It can be assumed that the watch here was an attempt by Rolex, interestingly exactly at the same time, to gain experience with such experiments.
In fact, reference 5028 is generally known to be fitted with centre seconds. Its sister model with subsidiary seconds is the equally rare reference 5026. The present watch is a fascinating, yet unexplainable hybrid between these two models.
