I'm selling this because I bought it, but it wasn't what I expected. Thank you. ◎ A reproduction model of the classic Tropic strap, a masterpiece of its time, is now available from a Swedish watch strap specialty store! ◎ This strap is made of high-quality 【FKM】 rubber, known for its excellent durability, chemical resistance, oil resistance, and resistance to extreme temperature changes. ◎ Dust is less likely to adhere to the material, and it is very flexible, so it has the characteristic of being very comfortable on the wrist from the beginning. ◎ Please enjoy the exquisite texture that is different from ordinary rubber materials. ☑︎︎︎︎︎︎︎ Brand new, unused ︎︎︎︎︎︎☑︎︎︎︎︎︎︎ Free shipping (anonymous delivery) ︎︎︎︎︎︎☑︎︎︎︎︎︎︎ Immediate purchase welcome ☑︎ Ships within 24 hours ︎︎︎︎︎︎ 【Easy to attach and detach】 Quick release is adopted, making it easy to replace the strap without tools. 【Size details】 Strap width: 20mm at the watch side / 18mm at the buckle side Strap length: 130mm at the tip / 80mm at the buckle side (excluding the buckle) It also has a leather-like texture, so you can use it comfortably all year round.
