Off the back of Patek's amazing looking case - I've placed an order with Simon.
I'm fortunate enough to own a SAB Westminster case in London Tan with full wraparound straps, so will have a pretty solid benchmark to compare it against.
To provide something a little different to the SAB, I've ordered a short strapped briefcase in Sedgwick Dark Havana bridle leather. 3 compartments (with the centre compartment a little larger than the others to accomodate bulky items). Full size rear pocket. Chrome plated brass hardware. Shoulder strap,
Here's a sample of the Dark Havana leather. I was expecting something near black based on Sedgwick's website, but the sample is just the shade of brown I was after:



And a selection of chrome locks to choose from:

Hopefully will be completed by the end of January - will keep this thread updated with pics (that Simon is kind enough to send you as your order progresses).
