I came across a 1A and a 1BT in the market, but both no B & P. The guy has a very strong reputation, so I am not worried about fake watches. However, 1A does not have the original strap and buckle selling at more or less USD10.5K, 1BT has the original strap and buckle selling at USD9.5k. Patina and watch conditions are very similar in both watches. Shall I go for it or I shall wait for a 2A or 2BT (which I love to have)???
