If you have been searching for a rubber strap for your Rolex, there are two brands that you are probably familiar with – Everest and Rubber B. In this review, we will take a close look at a rubber strap from Rubber B that fits the GMT-Master II (please also see my Everest rubber strap review). Coming soon, a comparison review where I will be putting the Everest and Rubber B straps head-to-head to see who reigns supreme in the Rolex Aftermarket Rubber Strap Division (a first for Life of a WIS!).
Overall Design | 18 out of 20
This black Rubber B vulcanized rubber strap is made in Switzerland and comes with a 316L stainless steel tang buckle in satin brushed finish. According to Rubber B, this particular model is engineered to only fit the Rolex GMT-Master II and Rolex Daytona. The strap features a raised middle section that starts from the lug and it gradually disappears before reaching the other side of the strap. In addition, there is a perpendicular line that runs near the edge of the lug, giving the Rubber B a distinctive look. The rubber strap is very smooth and flexible. If I had to describe the design with one word I would say “sleek”. The way the strap integrates with the case is nearly flawless and the design lines are simply beautiful. Rubber B also offers this strap in various colors and in deployant form.
Quality and Durability | 19 out of 20
For the price, I expect the quality of this strap to be top notch, and Rubber B does not disappoint. Even after several months of use and abuse, this particular strap is still in fantastic shape and will probably last many more years (if not forever). Inevitably, there are some signs of wear, which is natural for a black rubber strap (mainly slight marks from the tang buckle). When the strap was new, it was completely flawless. The spring bar on the tang buckle works just fine, but it would have been nice if Rubber B opted for the more secure screw-in tang buckle option, especially at this price point.
Operation and Fitment | 15 out of 20
One of my biggest issues with this Rubber B strap is fitment. Sure it fits perfectly between the lugs after it is installed (case integration is fantastic)… but the problem is getting it installed in the first place. I even contacted Rubber B to ask them if it was normal that installation was this difficult and their reply was yes. For some odd reason (or should I say design issue), this particular strap (which fits the GMT-Master II and Daytona) is harder to install compared to their other straps and they are aware of this issue. The problem comes when you try to align the spring bar with the holes on the lugs. Once the first side is inside the hole, you really have to wiggle and force the other side of the spring bar to enter the hole on the other side… it usually takes a few tries before the strap will cooperate (not to mention a significant amount of force). I noticed that installing it on the GMT-Master II was significantly more challenging than on the Daytona. Changing a strap should not be this difficult, so points were deducted for this. Thanks to the perfect curvature of the tongue on the tang buckle, operating the strap is much easier than installing it ;-).
Comfort | 19 out of 20
This Rubber B strap fits very comfortably on my 6.5" wrist. As a plus, the amount of excess strap on the other side is minimal, just the way I like it. Although the strap does have 7 holes so that it can fit a large range of wrist sizes (5.5" to 8.25" according to Rubber B), the holes are a bit too far from each other in my opinion. Therefore, the chances of your "perfect" fit being in between two holes is considerable. In my case, I got lucky as my perfect size can be found in one of the existing holes. On the back side of the strap, there is a slight indentation throughout the entire strap, which allows the strap to breathe when you sweat. Finally, the relatively flat design of the tang buckle and no sharp edges, makes this strap a pleasure to wear.
Value | 16 out of 20
The retail price for this strap is a steep $240, which is more like OEM pricing rather than aftermarket. However, the quality and finish on this strap is excellent, making the high price of the strap a bit easier to accept. In general, I feel that most watch accessories (such as straps and buckles) are grossly overpriced... but we watch nerds need these unnecessary items, so we will eventually give in and purchase them no matter the cost.
TOTAL SCORE: 87 out of 100
Because your Rolex deserves to be different.
