Before you buy

- Higher priced than simpler Nivada three-hand models
- Vintage-inspired bezel/chrono layout is busy by design
FAQ
Is the Chronomaster Aviator Sea Diver automatic or quartz?
The Chronomaster Aviator Sea Diver is automatic. The Landeron 72 winds itself from the motion of your wrist, so it needs no battery. Left unworn it winds down and stops, then restarts once you wear it or wind the crown.
What movement does the Chronomaster Aviator Sea Diver use?
The Chronomaster Aviator Sea Diver is powered by the Landeron 72 from Landeron, an automatic caliber. Being automatic, it winds from the motion of your wrist and needs no battery.
Does the Chronomaster Aviator Sea Diver have a date?
No — the Chronomaster Aviator Sea Diver has no date display. Some movements in this class can drive a date, but this one is specced without it, leaving a cleaner, more symmetrical dial. If a date is essential, look for a dated variant or a different model.
How water resistant is the Chronomaster Aviator Sea Diver?
The Chronomaster Aviator Sea Diver is rated to 100 m. That covers swimming and snorkelling, though hot water and direct high-pressure water are best avoided, and it is not intended for scuba diving. Whatever the rating, avoid operating the crown or pushers underwater, and have the gaskets checked periodically to keep it reliable.
How big does the Chronomaster Aviator Sea Diver wear?
At 41 mm across with a 48.5 mm lug-to-lug and 15.85 mm thick, the Chronomaster Aviator Sea Diver wears as a modern medium-to-large watch. Lug-to-lug is the measurement that really decides fit, since it sets how far the case spans the wrist — 48.5 mm suits most wrists, and smaller wrists especially should check that figure.
What movement does this Chronomaster use?
The official 41mm Broad Arrow page lists a Landeron 72 automatic chronograph movement.
How water resistant is it?
Nivada lists 10 ATM / 100m water resistance.
Is this every Chronomaster variant?
No. Nivada sells multiple Chronomaster variants; this record is scoped to the official 41mm Broad Arrow configuration.
