Quality shows on the underside
With a watch strap, quality is not determined by the upper leather alone. The material on the underside is just as important – after all, it sits directly against your skin.
With inexpensive straps, manufacturers often cut corners on the lining leather. The result can be a material that traps heat, transfers colour or irritates the skin. With dropshipped straps from an unknown source, it is also often unclear which substances were used.
Some manufacturers therefore combine leather on the upper side with rubber underneath. That can be practical – but it is not necessary when truly high-quality lining leather is used.
