Two gold-dial Day-Date 128238 references exist in this catalog, and the distinction matters. This version adds factory-set diamond hour markers to the gold sunburst face — transforming a business-formal watch into something that crosses into jewelry territory. The diamond indices catch light from a different angle than the sunburst pattern beneath them, creating two simultaneous layers of brilliance on a single 36mm dial. It is the sort of detail that separates a Day-Date from every other gold dress watch.

The 128238 Up Close: Case, Dial and Bracelet
The gold sunburst dial serves as a canvas for 10 diamond hour markers — each stone set into a tiny gold surround that integrates with the overall dial tone. Under direct light, the diamonds flash white against the warm gold background; in lower light, they recede into subtle points of texture. The fluted bezel adds a third layer of light interaction above the dial plane.
The President bracelet maintains full yellow gold consistency from end link to concealed Crown clasp. For the non-diamond gold dial variant, or other Day-Date configurations, visit the Day-Date collection.
