Here's a classic from Breitling, the Navitimer 7806 with glossy black dial and super-sharp case.
Why are these Navitimers prized by collector? The size, for one thing: a massive but wearable 41mm across by 48mm from lug to carved lug.
The intricate but readable dial in black and white, perfect for pilots or other navigators.
The gold-cap and stainless steel back is a cool blend of metals and very popular.
This one is powered by a Valjoux 7750 that is serviced and keeping excellent time.
