Hublot HUB8100

HUB8100 is a manual-winding in-house caliber introduced by Hublot in 2023 as part of the HUB81xx family. It combines a chronograph with a perpetual calendar and rattrapante (split-seconds) function—a notably complex configuration that displays hours, minutes, seconds alongside calendar information while allowing two separate timing events to be recorded simultaneously. The movement reflects Hublot's emphasis on high complications within its in-house portfolio. Production remains limited.
