Although highly popular with watch enthusiasts, some criticise the case size and depth for comfort or design reasons.To put a smile on these clients' faces, IWC has designed a smaller and slimmer Pilot's Watch Automatic 36 which, as the name suggests, has a 36mm steel case. The self-winding 3511 calibre powers the time and date functions along with the 42-hour power reserve.The dial comes in three colours: silver, slate and blue. The central disc bearing the black and white Arabic numerals and luminescent hour, minute and seconds hands stands slightly above the minute track. A black-on-white date display appears at 3 o' clock.Price upon request.By Sharmila Bertin

AP's numbering system?
Hey everyone... Can someone please explain to me the numbering system used by AP on our case backs? Not referring to the Serial number (E, F, G H#####) but the N*####... Is that a sequence # for the model? Thanks

Serial Number Range Question
I have a 16610 (D serial) that i purchased new about 12 years ago. I also have a 16710 (also D serial) that i purchased second-hand. Per the warranty papers it was originally purchased about 3 months after i bought my sub.The actual serial numbers of the 2 watches differ by about 18,500. I'm just curious about this but am trying to figure out how close the production dates of these 2 watches might be. Any sense of production numbers in 2005/2006? in advance
