Concord’s Biretrograde doubles up on date of the week and day and is offered in both platinum and rose gold. Unapologetically bold and masculine, this timepiece is bound to get noticed: if you can get your hands on one, that is. There’s a limited-edition release of 50 platinum and 150 rose gold options, and that fine craftsmanship means ultimate precision, Concord C101 mechanical automatic movement, and a 42-hour power reserve. Plenty of contrast, depth, and style here.[via watch happening]
