Explorer ll 42mm (2021-current) -226570

22mm Universal Rubber Straps for Rolex Explorer II

The 22mm lug width is standard on the modern Explorer II, covering the 216570 introduced in 2011 and the current 226570. These are listed as universal fit rather than curved ended, which suits the slightly different case geometry of the larger 42mm case. The range covers black, white, grey, blue, red, orange, yellow, green olive, Miami blue and multiple camo patterns. All standard rubber options are €76.50 with the current discount. If you want to add Swiss made spring bars, those are available separately.

FKM Vulcanized 22mm Straps – Built for Daily Wear on the Explorer II

The modern Explorer II gets worn hard. It was designed as a tool watch and most owners use it that way. FKM Vulcanized holds up better to that kind of use than standard rubber — it's hypoallergenic, resists UV degradation, and keeps its shape after months of daily wear in heat, water and sweat. Available in black, white and Marbella Blue from €140, with options for both standard buckle and Rolex deployant clasp. If the 226570 or 216570 is your go-to watch and you want a strap that lasts as long as the watch does, FKM is worth the difference in price.
