Customers praised this FKM rubber strap as "super comfortable," lightweight, and great-looking. Many appreciated its durability, soft feel, and quick-drying properties. However, some found sizing challenging for larger wrists (8+ inches), with concerns about length and fit adjustability being too tight or loose.

Great Utility Strap

This is my first single-pass strap and my first experience with the FKM material. So far I've been very pleased with both and have used it on my Citizen Promaster. I was specifically looking for a strap that would be durable and chemical resistant due to the nature of my job.

10/10 Definitely Recommend

Definitely recommend for those who have a thicker watch that’s top heavy there aren’t many options out there that allow you to wear something beside a bracelet without adding a good amount of height and presence to your watch. Some straps add so much height that it feels like the watch head is on a pedestal which is then sitting on your wrist. *Enter Anchor Strap Single Pass FKM* this strap adds virtually little weight, enhances the overall look of your watch, very durable and soft. Some rubber straps have given me skin irritation but this does not. It’s hard when you’re excited about a strap only to find out that it just doesn’t feel as premium as you thought, the straps by Anchor Strap feel as good as they look.

My new favorite strap!

These have become may favorite non bracelet straps. The single pass makes them thin and the rubber is comfortable. Have them in several colors now. But the black on black pvd is my favorite.

Excellent Rubber Nato

I haven't been this excited about a new watch strap in awhile! I have a black Tudor rubber nato that I really love but haven't seen the type anywhere else until now. Now I've got options for multiple colors and multiple lug widths! And the quality is right up there with the OEM strap that costs three times as much. Ordering more today!

FKM Single Pass is excellent for my Omega Planet Ocean 45

The FKM Single Pass is excellent for my Omega Planet Ocean 45.5mm . The quality is superb and well worth the money. For an aftermarket strap, this is top!!!

Single Pass Rubber strap

Just got mine today . I’d say one of the most comfortable straps I have ever had and it’s not too long considering my small wrist. Plan to get more.

Can't Say Enough Good Things!

I just received the Single-Pass FKM Rubber Strap in Navy Blue yesterday and had it installed on my Tudor Black Bay 58. I can't say enough good things about the look & feel of the strap and how it looks with the BB58.

Great-Looking Strap… Better Suited for Lighter Watches

The strap is well made, comfortable, and looks great. The materials and craftsmanship are excellent, and it definitely gives the watch a clean, attractive look.
My only issue is that it’s so thin and flexible that it has a hard time keeping my Marathon TSAR from wandering around my wrist unless I cinch it down tighter than I’d like. To be fair, the TSAR isn’t exactly a featherweight—although it’s actually lighter than quite a few other watches with 20 mm lugs. I suspect this strap would be fantastic on lighter or medium-weight watches, but if you’re pairing it with a chunky tool watch, be prepared to wear it a little snugger.
Overall, it’s a very nice strap. I just think it shines brightest with watches that aren’t trying out for the heavyweight division.

Love this strap

Love this strap, very comfortable and a great option for something waterproof that can be quickly swapped on a single pass or nato setup

Great band for a high fitting watch

Great band for a high fitting watch. Drops it down a little on the wrist. Great for smaller and mid sized watches. Bigger or heavier watches you may want to get their deployment band.
