I used an old trick that I hesitate to share: patience! TS at an AD, waited a year. I ordered immediately after it was announced at SIHH. 5270 at the Salons in Geneva and RO at the AP boutique. For the RO, I put my name on the list about 3 or 4 years ago... as life often works that way, they all came in within 3 months of each other... my banker was not too happy .
