10.BANGLIN 100m Digital Submersible Waterproof

Score: 7/10
This watch is a strong contender for anyone seeking a highly affordable, functional, and genuinely water-resistant digital watch without breaking the bank. It’s often chosen as a “beater” watch for activities where you wouldn’t want to risk a more expensive timepiece.
Pros:
- Excellent Water Resistance (10ATM / 100m): This is the standout feature. Users consistently report it holding up well during swimming, showering, snorkeling, and even light diving. The 100m rating means it’s suitable for surface water sports and general immersion, though not typically recommended for serious scuba diving despite the brand’s occasional claims.
- Affordable Price: This is arguably its biggest selling point. It offers a surprising amount of functionality and water resistance for its cost.
- Clear Digital Display & Backlight: The large digital numbers are easy to read in various conditions, and the electro-luminescent backlight aids visibility in low light.
- Multiple Functions: It includes essential features like an alarm, stopwatch, countdown timer, dual time zone display, and hourly chime, making it versatile for sports, travel, and daily use.
- Comfortable and Lightweight: Made with a soft PU (polyurethane) strap and ABS case, it’s designed to be comfortable for extended wear.
- Long Battery Life: The CR2025 battery is reported to last for 1.5 to 2 years, reducing the hassle of frequent charging or battery changes. It’s also replaceable.
- Shock Resistant: Designed to withstand minor knocks and bumps, which is beneficial for an active lifestyle.
- Simple to Use: Customers generally find it easy to set up and operate the various functions.
Cons:
- Build Quality (Budget Materials): While durable for its price, the ABS case and resin dial window are not as premium or scratch-resistant as materials found in higher-end watches (e.g., stainless steel, mineral glass, or sapphire crystal). It might show wear and tear more quickly.
- Aesthetics: The design is purely functional and utilitarian. It’s not a fashion statement, and some might find it a bit chunky or basic-looking.
- Button Durability: While the water resistance is generally good, some users might question the long-term integrity of the buttons under frequent underwater use. It’s usually advised not to press buttons underwater on any watch unless explicitly designed for it (which this watch claims, but caution is still wise on budget models).
- Alarm Volume: The alarm and hourly chime are present but might not be loud enough for all users or in noisy environments.
- Countdown Timer Functionality: Some reviews indicate that the countdown timer only stops at zero and doesn’t have a count-up feature from zero, which might be a minor inconvenience for some.
Approx. Price on Amazon UK: £15 – £25
Key Considerations When Buying a Sailing Watch:
- Your Sailing Style:
- Racing: Prioritize dedicated regatta timers, sync functions, and clear, large displays (Optimum Time, Ronstan, Gill).
- Cruising/Offshore: Focus on GPS navigation, robust battery life, weather features (barometer, storm alerts), and durability (Garmin Quatix, Suunto 9 Baro, Coros Vertix 2, G-Shock).
- Casual/Day Sailing: A robust, water-resistant watch with a simple timer might suffice (Timex Ironman, basic G-Shock).
- GPS & Navigation: Do you need real-time position, mapping, and route tracking on your wrist?
- Marine Integration: Do you have Garmin marine electronics and want the watch to act as a remote display or controller?
- Smartwatch Features: Do you want health tracking, notifications, and contactless payments alongside your sailing tools?
- Durability & Water Resistance: Essential for any watch on the water. Look for at least 5 ATM (50m) for splashes, and ideally 10 ATM (100m) for more rigorous use or accidental submersion.
- Battery Life: Critical for longer trips, especially with GPS use. Solar charging can be a game-changer.
- Display Type: MIP (Memory-in-Pixel) displays are excellent in bright sunlight and efficient. AMOLED offers vibrant colours but uses more power. Large digits are key for race timers.
- Budget: Sailing watches range from very affordable basic timers to highly expensive smartwatches.
