HOW DO WE DATE THIS WATCH?
Although we have the papers for this watch, the guarantee card does not have a date on it. However these watches were made in the late eighties, and the instruction booklet is dated for 1989 so the watch is likely to have been made circa 1989.
CONDITION
Porsche Design are now an independent watchmaker, but between 1978 and 1995 they had IWC make their watches for them and they were dual branded. You can read more about their history here. IWC were the pioneers in using Titanium as a case and bracelet material, and it is fitting that a Porsche Design should incorporate strong and lightweight materials. Including the bracelet, this entire watch weighs only 72 grams. The bracelet is especially clever, as each link is exactly 5mm to allow military personal to use the bracelet to measure distances on maps (True!). It is important to find one of these watches with a long enough bracelet, as links are hard to source, but this one is a good size for most people. The case itself is also clever, not having any obvious pushers sticking out but instead they are recessed into the case design. The mechaquartz movement in this watch is calibre 630, which was shared with Jaeger-LeCoultre and in production from 1987 for 20 years. Being quartz the timekeeping is fantastic, but the mechanism to operate the chronograph is mechanical (hence Mechaquartz). This gives you the instant reset and smooth sweep of the chronograph centre seconds hand, while the constant seconds at six is ticks once a second. You can also get an IWC Chronograph in the Pilots, Ingenieur and Da Vinci ranges with this same movement. We will install a brand new battery before sending the watch out to the new owner. The dial is very busy, cramming in three subdial, a crescent cut out for the moon phase and a date window at 4.30. On the whole it is easy enough to read, but the choice of using gold on blue for the date is a struggle to read at a glance.
