STT1987, I agree that the TO1 is a good looking watch. I have one on order!

To answer your questions:
1) Yes, I ordered and received 3 watches from them in the last 12 months.
2) Customer service is the best you can encounter on line. Once you order they will immediately confirm through e-mail. You will be notified to make payment when your watch is ready to be assembled. I made payment via TT. They will ship the watch about two weeks after payment using Fedex with tracking number e mailed to you. All along the process you can e-mail them on your order (and make changes if you want) and they will answer promptly. The only 'problem' is the long waiting period from your order to the watch assembly date - you have to wait for your turn which could take up to 3 months. Sorry, no shortcuts (unless you fly to Germany and buy from Manufaktum)
3) When you order and input an address outside EU, it will automatically take out the VAT. You can view the final price without VAT before you confirm the order.
4) No hassle at all from our friend at Customs. Fedex clears everything for you. If you order crocodile strap, they will ship the crocodile strap separately to avoid problems at Customs. The crocodile strap comes with Cites certification. You get a normal leather strap with the watch whilst waiting for the crocodile strap to arrive.
Go ahead, put in your order, and go through the 'torture' of 3 months wait and the enjoyment of finally receiving the watch!
