the IWC Doppelchronograph is a really good (and for sure a classic watch in the near future)
watch with a sporty optic for reason of the third pusher - a nice add on/complication - in
a enyojable dimensioned case size

but don't go for a 3713

go for a 3711, because these first execution watches had a special kind of domed saphirre
crystal, that really looks like a plexi

for the different not domed crystal in the 3713 they also had to change the middle case construction

IWC 3711 yellow gold version

3711 is the much more nicer watch for collectors, that usually have there eyes on vintage watches

watches like IWC Doppelchronograph showing prices, that continue to languish on a acceptale level
over the last years, so in my opinion a good decision far away from all market "high end price level"
