Who we are

Welcome to +4 Design

At +4 Design, we are passionate about crafting handmade and customized watch straps of exceptional quality. Each piece is meticulously hand-sewn by Japanese master craftsmen, using only the finest materials sourced from prestigious tanneries.

Expanding our horizons, we now offer an exclusive collection of camera straps. Our silk cords are sourced and made in Japan, ensuring authenticity and craftsmanship that stand the test of time.

Born from the shared vision of four dedicated creators, +4 Design was founded to fill a gap in the market for luxurious, high-quality watch straps and small leather goods. We take pride in designing unique, stylish accessories with meticulous attention to detail, catering to watch and accessory enthusiasts like us.

Our mission is to provide exquisite products that complement a variety of styles and preferences. We hope you find something truly special as you explore our collection.
