Both watches have hand-sewn, crocodile leather straps with cut edges and are of excellent quality. The Patek Philippe strap shines with glossy clear lacquer, while the Lange one has a matte finish.
Each strap has a simple prong buckle, in keeping with the watches’ overall minimalist design. A folding clasp is more elaborate and doesn’t necessarily enhance wearing comfort. Patek Philippe facets its prong very beautifully, but merely bends it around the crosspiece. The polished buckle is a good match for the watch and is instantly identifiable as being from Patek Philippe. Lange mills its prong from a solid block of precious metal and reinforces the buckle with an additional crossbar. The strap is guided through the buckle so that it scarcely needs to be bent; the clasp and strap fit closely on the wrist. The name “Lange” appears on the buckle in clear, capital letters.
