Another! what strap thread - for a Mondaine

[bigandclever]

Hello All,

Picked up a lovely Mondaine auto date watch this afternoon, and already I want to update it a little. I think the strap, while of very nice quality, is a little too 'delicate' - I'd prefer something slightly thicker, and I quite fancy a deployant clasp too. I know Toshi straps come recommended but at 4mm I suspect they might actually be too thick for the watch (I'll drop him a line anyway).

So, can anyone recommend either a suitable strap, or maybe a strap maker? I'm thinking black leather with white stitching, deployant clasp, happy to pay for a quality product.

Cheers!
