Buying Guide
- Movement and accuracy: Look for NH34 or NH35 automatic calibers for reliable timekeeping and a GMT hand that can be set independently. Expect daily accuracies within a few seconds to tens of seconds depending on regulation and usage.
- GMT function: Ensure the GMT hand is easily adjustable and clearly differentiated from the main hour hand. Decide between a 24-hour scale or a dual-time display based on your travel patterns.
- Water resistance and case material: For diving use, prioritize 200m–300m water resistance, a robust stainless steel case, and a scratch-resistant sapphire crystal. Helium escape valves are a plus for professional saturation diving.
- Bezel and luminescence: A unidirectional bezel with a 120-click mechanism aids timing underwater. Lume quality on hands and indices is crucial for legibility in low light.
- Bracelet and comfort: Tool-free adjustment clasps and diver extensions improve fit over wetsuits. Consider bracelet material and finishing for long-term wear.
- Maintenance and warranty: Automatic watches require periodic servicing to maintain accuracy. Check manufacturer warranties and authorized service options.
- Size and wearability: Dive watches often wear larger; ensure the diameter and lug-to-lug length suit your wrist for comfortable daily wear and while diving.
- Brand and after-sales support: Reputable brands with clear documentation and service centers can reduce risks on long trips or remote dives.
