Introduction
The first 'modern' Daytona- the 165XX model, was released in 1988 as the successor to the Valjoux 72 based 4 digit models (which have been in production since the 1960s). Manufactured in a multitude of arrangements, with contrasting case materials and dial configurations, the watch was the first Rolex chronograph to feature an automatic winding movement. The movement in its inception was a Zenith 400 caliber, prior to Rolex making over 200 of its own modifications, after which it became the caliber 4030.

THE LAST OF ITS KIND
A very late production example, this 16520 features the 'SWISS MADE' designation at the bottom of the dial, and a solid endlink bracelet with polished center links. 'SWISS MADE' on the dial denotes the dial having luminova based luminous instead of tritium.
THE MOVEMENT
The Zenith-based Caliber 4030 was used in Daytonas from 1988-2000. It oscillates at 28,800 beats per minute. This was the last time Rolex was to use a movement not designed in-house.
TIMING MACHINE READOUT
This reading was taken (crown down) with a ONEOF Accuracy Boutique Edition timing machine at time of cataloging. It is provided as a courtesy only, and shall not be construed as a warranty or guarantee of any kind. Please refer to our terms and conditions of sale for more information.
Condition
The overall condition of the watch is exceptional. Superficial faint scratches can be seen on the bezel and polished center links of the band, however these are minor and do not detract from the beauty of the piece. Dial and hands are flawless, with no apparent spotting or blemishes.
Our Perspective
It is hard to imagine that the 16520 was launched over 30 years ago! Still as modern looking as when it was first released, this the Zenith caliber based Daytonas are amongst my favorite. With new Daytonas' fetching prices that are higher than ever, these now vintage examples are worth some serious consideration.
