I needed a strap for my new 1815 as the original is too small. Just to satisfy my curiosity I ordered a custom strap.
I am very happy with my new strap and without question it is at least of equal quality to the excellant Lange strap.
It took only 17 days from the time I placed my order for it to arrive at my door step. Additionally it was 2/3 the cost of a new Lange.
