When you attach a military, nato style strap to your watch case, your watch is more secure than any other type of strap.
This extra security comes from the fact that your watch case will be attached to two different points; also known as the spring bars which are fixed in the lugholes of your watch. Let's say your watch hits a certain object such as a fence, doorknob and as a result, one spring bar fails then the second one will keep the watch attached to the strap.
These premium quality seat belt slip thru watch bands are made from a tightly woven nylon fabric with a silky finish. Extremely durable and comfortable to wear. Finished with laser sealed holes and heavy-duty, brushed, solid stainless steel silver buckle.
