This is a nice idea for boys who want to be just like their fathers. These Schaffhausen father-and-son watches are certainly not cheap, but the Pilot design with rhodium-plated dial, cockpit design and crocodile-leather straps are classic creations. The only real difference is that while the adult version is platinum, the son's is made from resistant stainless steel.
