Frequently Asked Questions
What does 20/16mm mean, for example?
For watch straps, two numbers like 20/16 represent the lug width and the clasp width in millimeters :
→ 20mm Indicates the lug width , i.e., the width of the strap at the point where it is attached to the watch . Always important!
→ 16mm indicates the clasp width , i.e., the width of the strap at the point where the pin or folding clasp is attached. Only of limited importance if you intend to use the original clasp of your watch.
Which leather watch straps are particularly durable and hard-wearing?
In general, all our leather watch straps are significantly more durable compared to those of other manufacturers. Each strap is reinforced internally with a special Fluco reinforcement that stabilizes the leather and protects it from deformation or stretching.
We primarily use full-grain leather , which is the top and most robust layer of the hide. This leather is particularly dense, breathable, and develops a beautiful patina over time. Some models are made from top-grain leather or split leather – the specific type of leather is indicated under each strap.
You can find more details about the differences between the types of leather in our article "Types of leather at Fluco - Full Grain, Top Grain & Split leather compared".
In short: Fluco straps are more durable than ordinary leather straps – thanks to high-quality materials and our own reinforcement.
Which leather watch straps go well with classic automatic watches?
The following leather watch straps are particularly well suited for classic automatic watches:
-
Smooth calfskin leather – a timeless classic: elegant, simple, and comfortable to wear. Ideal for formal and classic watch designs.
-
Alligator or crocodile leather – a high-quality, elegant option that underscores the luxurious character of an automatic watch. Perfect for dress watches.
- Vintage leather watch straps – with a slightly aged look and patina, ideal for watches with retro or heritage design.
- Nubuck or suede leather – a matte, velvety surface that has a more modern, yet classic effect.
-
Brown or black leather: Universal colors like dark brown or black go with almost all classic automatic watches.
It's important that the color and finish of the strap match the case color and dial. A simple, high-quality leather strap emphasizes the watch's elegance and ensures a timeless look.
If you prefer something a bit sportier, the Fluco Hunter Racing with seam and perforation is a good choice – sporty, yet classic.
