Nebula’s A&S5101 caliber is a hand-wound movement that operates at 3Hz (21,600 vph) with 90 hours of power reserve between the two mainspring barrels. Its most distinctive feature is its seven classical-style bridges mounted radially around the movement and hold most of the components together. As usual, legibility is maintained by well-proportioned hands, and the hours and minutes track along the chapter ring.
