The Rolleiflex is one of the most famous camera series of all time. Its retro design, with twin lenses, a large waist-level viewfinder and a silver metal body covered in black leather, serves as the inspiration for a strictly limited-edition wristwatch marking the 100th anniversary of Rolleiflex.

MB&F's M.A.D.3 watch, part of its third M.A.D. Edition, pays tribute to independent watchmaker Vincent Calabrese by reimagining his signature jumping hours complication. This collaboration marks the first time MB&F's entry-level sub-brand fully conceals the winding rotor and bases a design on a historical watchmaker's work. The M.A.D.3 features a wandering jump hour mechanism, inspired by Calabrese's original Baladin design, which transitions between hours over three minutes instead of abruptly. The 40mm stainless steel watch uses a La Joux-Perret G111 base calibre with an in-house module, offering a 55-hour power reserve. Priced at CHF2,900, it's available via a raffle with limited editions for MB&F's Tribe and Friends. The design incorporates elements like the teardrop-shaped crown logo and a case designed by Eric Giroud. While the mechanism improves legibility, some users may find the hour markers confusing at 6 and 9 o'clock. The watch balances affordability with craftsmanship, reflecting Calabrese's philosophy of progressive timekeeping.
