About the Special Projects family
Special Projects is a collection MB&F began in 2025, for its 20th anniversary, with the SP One. It sits between the Horological and Legacy Machines and is the brand's smallest and simplest watch so far: a 38 mm, pebble-like case made of a case band and two sapphire domes, showing hours and minutes only, with a hand-wound movement and a 72-hour power reserve.
The SP One is made in platinum and in red gold, the two references listed here. As a recent model, buyers will expect the complete set and the original warranty.
