Last time we published an article titled "Smartwatch Strap: Why Silicone Is the Dominant Material?". We received numerous comments and messages on the platform.
Many netizens said: "Nowadays, the mainstream material is fluorine rubber." "Fluorine rubber is much more practical than silicone." "Just try the FKM watch strap and you'll know the difference."
Today, we will specifically talk about fluorine rubber watch straps - what exactly is it? How is it better than silicone? And why are more and more high-end brands using it?
1. What is fluorosilicone rubber?
Fluororubber, abbreviated as FKM in English, refers to a synthetic polymer elastomer whose main chain or side chains contain fluorine atoms.
It sounds very professional, but just remember this: The introduction of fluorine atoms gives fluororubber its outstanding properties that no other rubber can match - high temperature resistance, oil resistance, chemical corrosion resistance, aging resistance, and also excellent physical and mechanical properties.
When used on watch straps, the advantages of fluorosilicone become very obvious:
Rich in texture: Higher density, with a luxurious "pressing" feel when handled.
Soft and skin-friendly: The texture is smooth and delicate, and it doesn't cause discomfort even after wearing for a long time.
Allergen protection safety: Few additives, friendly to sensitive skin
Durable and stain-resistant: Resists dust accumulation, doesn't fade easily, and becomes more luxurious with use.
Some users have described the feel of the fluorine rubber watch strap as: "As delicate as skin, yet as cold and stern as metal". This superior texture is something that ordinary silicone cannot offer.
II. Who is using fluorosilicone?
Fluorine rubber watch bands are no longer a niche product.
Major smartwatch brands such as Apple, Huami, Xiaomi, Huawei, OPPO, and Vivo are all extensively using fluorine rubber straps. The WATCH FIT and WATCH GT series from Huawei come with fluorine rubber straps as standard.
Not to mention those top-of-the-line watches starting at six figures (such as Audemars Piguet AP and Richard Mille RM) - their original factory straps are made of FKM fluororubber.
From top luxury items to mass-market consumer electronics, fluorine rubber watch straps are becoming the choice of an increasing number of brands.
III. Why is Fluorine Rubber Becoming More Popular?
The reason is actually quite simple: Consumers are becoming increasingly "informed".
In the past, when people bought watches, they focused on "cheapness" and "beauty". Now, they pay more attention to "whether it feels comfortable to wear", "whether it will get old after long use", and "whether it might cause allergies".
Fluorine rubber precisely meets these upgrade requirements:
Comfortable to wear: Soft and skin-friendly, no marks or pressure marks even after long-term use.
Easy to use: Resistant to dust, non-slip, sweat-resistant and dirt-resistant.
Looking at it, it's of high quality: the texture is dense and there is no cheap sheen.
Skin-friendly: Less likely to cause allergies
In simple terms: Silicone solves the "existence" problem, while fluorine rubber solves the "quality" problem.
With the number of smartwatch users exceeding 420 million, consumers' demands for watch bands will only continue to rise. It's only a matter of time before fluorosilicone becomes the mainstream.

To sum up
The fluorine rubber watch strap has become the preferred choice for an increasing number of brands and users. The key reason lies in just four words: "Easy to use and durable."
It has a more luxurious texture, is dirtier-resistant, more skin-friendly and less likely to cause allergies. Although the price is higher, for users who value the wearing experience and long-term use, this investment is worthwhile.
Silicone is "adequate", while fluorocarbon rubber is "excellent". The difference between the two is obvious from the very first use.
