Mondaine's Automatic is the only Mondaine you never have to buy a battery for. Because it's automatic it's the only Mondaine where the second hand sweeps seemlessly rather than clicks.
The Mondaine Automatic Day Date has a see-through back so you can see the mechanism at work. It winds itself through the everyday motion of the owner's wrist. It has one other cool feature - you can set the day function to give the days in German or English. Who said too many Australians were mono-lingual ?
Steel polished 40mm diameter day/date display, white dial, black leather 20cm strap, automatic. And priced accordingly.
