Manufacturing techniques for watch straps

What does cut strap actually mean and what are the differences to a fully remborded or semi-remborded leather strap?

What characterises a leather strap “Made in Gemany” and how many work steps are required for this?

Cut strap (approx. 70 work steps)

The cut strap is the most common, but rather simple leather strap. It consists of a three-layer material - upper leather, filling material and lining leather. The leather is cut by using a cutting tool and the edges are then varnished.

With around 70 work steps, it is somewhat more complex to produce than the semi-remborded leather strap.

Semi-remborded or semi-crowned leather strap (approx. 50 work steps)

With the semi-remborded strap, the upper leather surrounds the body of the strap and the lining leather forms the end at the bottom. In contrast to the full remborded strap, the upper leather is not covered and sewn under the lining leather. It is therefore not the seam that holds the strap together but, as with the cut strap, only the adhesive. Due to the durability is this the optimal production method as it shows no open edges.

This production method could only be implemented with modern, environmentally friendly adhesives and the only approximately 50 work steps have lead to economical consumer prices.

Remborded or full wraparound finish leather strap (approx. 100-120 work steps)

With the full remborded leather strap, the upper leather is wrapped around the filling material and sealed from the lining leather by adhesion. On the inside of the leather strap is a breathable filling material which leads to a better ventilation effect (“aero lining”). All the layers are glued with each other. A thread is only a design feature. Semi- and fully remborded leather straps combine softness - depending on the upper leather - with high stability and durability.

With approx. 100-120 work steps, it is quite complex to produce, which is why it is preferably used for high-quality bracelets.
