The Mares Sirius Hunter, awarded by Apnea Passion Magazine as the Best Choice 2025 in the freediving and spearfishing watch category, is not only one of the most advanced dive computers available today but also offers a practical and stylish customization option thanks to its interchangeable straps.
Designed for freedivers and spearfishers who want to personalize their equipment, the Sirius Hunter straps combine comfort, durability and a quick replacement system, making it easy to adapt the watch to your style or equipment.
Quick Release Strap System

One of the most practical features of the Mares Sirius Hunter is its quick release strap system. Replacing the strap takes only a few seconds and requires no special tools, allowing users to switch colours quickly and easily whenever they want.
Beyond its interchangeable straps, the Sirius Hunter stands out for its premium construction, intuitive user interface and comprehensive dive functions for both freediving and spearfishing. It also includes useful training modes for pool sessions and a reliable Bluetooth connection to the Mares App, where dive profiles, statistics and performance data can be downloaded, stored and analysed.
Seven Colours to Match Your Style
The Mares Sirius Hunter straps are available in seven different colours, offering plenty of possibilities to personalize the watch.
The standard version comes with the classic black strap, while additional colours include:
- Blue
- Cyan
- Military Green
- Red
- Orange
- Yellow






Buying two different colour straps or mixing them with the standard black one, can give the opportunity to reproduce the colours of your preferred football team, for example.


All straps are available through Mares authorized retailers.
Comfort, Strength and Reliability
Manufactured from high-quality soft silicone, the straps provide excellent comfort even during extended diving sessions while maintaining outstanding durability against salt water, UV exposure and repeated use.
Their optimized thickness and width ensure excellent strength without compromising flexibility.
Each strap features two silicone passages, providing an extra-secure closure that minimizes the risk of accidental opening during freediving or spearfishing sessions.
Ready for thick wetsuits
Every Mares Sirius Hunter strap is supplied with an additional long strap section, allowing the watch to be comfortably worn over thick winter wetsuits without sacrificing security or comfort.
Whether diving in warm summer waters or during cold-water winter sessions, the Sirius Hunter adapts perfectly to every situation.
A practical upgrade for every Sirius Hunter owner
The interchangeable strap system makes the Mares Sirius Hunter even more versatile. Whether replacing a worn strap, matching other diving equipment or simply choosing a favourite colour, users can renew the appearance of their watch in seconds while maintaining the same outstanding reliability underwater.
The combination of premium materials, secure fastening, multiple colour options and quick installation further confirms why the Mares Sirius Hunter was selected by Apnea Passion Magazine as the Best Choice 2025 for freediving and spearfishing watches.
