This year at Baselworld, Rolex debuted three new gold Daytonas with Oysterflex rubber bracelets. The precious metal case options are 18K yellow, rose, or white gold.
The patented Oysterflex rubber bracelet was first introduced in 2015 with the Yacht-Master.
Last year, Rolex introduced steel Daytonas with Cerachrom bezel, which are currently in short supply and high demand, and so this year is more of a line extension. It does likely mean we might see the steel Daytonas being sold with the Oysterflex bracelet in the near future as well.
As far as specifications, the case is still 40 mm, black monoblock Cerachrom is engraved with a tachymeter scale that is filled in with gold that matches the case. The caliber 4130 Rolex chronograph movement with 72-hours powers the watch. Water-resistance is 100 meters. Notably, the Oysterflex rubber strap is unique because it has flexible metal blades over-molded with a high-performance elastomer.
