Gymboss Plus interval timer and watch strap, White / Gray, loud beep and vibration, water-resistant

Gymboss Plus Bundle pairs a rugged, loud interval timer with a breathable watch-style strap so you can track rounds, rests and workouts hands-free outdoors.

Built for outdoor activity, this bundle combines the Gymboss PLUS interval timer — an enhanced, water-resistant unit with adjustable beep and vibrate alerts — and a secure, perforated watch strap that converts the timer into a wrist-worn device. The kit is compact, lightweight and designed to make interval training, running sets and stopwatch timing simple and reliable in wet or windy conditions.

How does the Gymboss PLUS keep alerts loud and noticeable outdoors?

The PLUS model boosts weather resistance and offers a very loud audible beep designed to cut through ambient noise common in outdoor settings. If a loud beep isn’t appropriate, you can switch to vibrate-only mode or lower the beep volume, giving you flexible notification styles for different environments.

• High-decibel beep for clear outdoor alerts
• Vibrate-only option for discreet notifications
• Adjustable alarm duration: 1, 2, 5 or 9 seconds
• Improved moisture resistance suitable for rain exposure

What timing functions does this timer include and how precise are they?

The Gymboss PLUS handles single or dual interval timing from two seconds up to 99 minutes, plus it includes a stopwatch and clock for everyday use. Auto-repeat mode cycles through intervals continuously, making it convenient for training sets and circuit work.

• Single or dual interval programming for flexible workouts
• Interval range: 2 seconds to 99 minutes
• Built-in stopwatch and clock for additional timing needs
• Auto mode for uninterrupted repeating intervals

How does the watch strap improve usability during runs and workouts?

The included watch strap converts any Gymboss with a removable belt clip into a wrist device, letting vibration transfer directly to your wrist for clearer tactile alerts. The strap is ventilated to reduce sweat build-up and uses black stainless steel hardware for durability during repeated use.

• Quick snap-in fit for Gymboss models with removable clips
• Perforated band promotes airflow and reduces sweat trapping
• Durable black stainless-steel hardware resists corrosion
• Improves vibration transmission for reliable alerts on the wrist

What are the size, power and durability details I should know?

The timer is compact — roughly pocket size — and runs on a single AAA battery, making it lightweight and easy to carry or wear. It’s built to resist sweat, impacts and light moisture common during outdoor workouts, though the battery is not included in the bundle.

• Dimensions: about 55 × 44 × 14 mm (2.25 × 1.75 × 0.5 in)
• Power: 1 × AAA battery required (not included)
• Sweat- and impact-resistant construction for active use
• Secure removable belt clip included if you prefer clipping to gear

This bundle is tailored for outdoor athletes, runners, group fitness instructors and coaches who need a clear, configurable interval timer that performs reliably in varying weather. Choose the Gymboss Plus Interval Timer and Watch Strap Bundle if you want a small, loud, and adaptable timing tool that fits on your wrist or clips to gear for hands-free training.
