Similar to manually-wound Daytonas, automatic ones may also present the colour-change effect of some elements of the dial. There is a difference though as with the old Daytonas it is usually the black elements that undergo this transformation. With the automatic Daytonas however, the elements affected are usually the white rings of the registers, which over time can display a wide variety of variations, from beige to chocolate. It is not an effect Rolex purposely planned, rather a consequence of the natural oxidization processes in the paint.
As manual Daytonas with color-shifted dials are highly appreciated by the market, the same is true of automatic Daytonas.

This aesthetic peculiarity can occur on versions from 1993 to 1997. This watch falls into this category, having been manufactured in 1996. Its wonderful case bears the W9 serial number and its dial has the layout collectors refer to as Mark V. The rings have changed to a tobacco hue and the process could possibly continue. This is a feature that may pleasantly surprise the future owner of this amazing timepiece.
