WATCH POP

I have a Saxonia (yellow gold, blue hands) on a black strap, and am thinking about changing to a brown strap. Does anyone know what the retail price is on Lange straps? Also, if I move to a deployant buckle (can't afford a Lange one), does anyone know the appropriate buckle size? Any scans of this watch/strap combination would also be much appreciated. Thanks.
Bob The brown strap idea is a good one, but look at other manufacturers like Camille Fournet and Kaufmann. Lange straps retail for around $250. Also, hold onto the black strap because you'll have two completely different looks for the watch.
