Gymboss Plus Interval Timer and Stopwatch, Violet / Pink, Wrist Strap Bundle — Loud Beep & Vibration, Water-Resistant

Gymboss Plus Interval Timer and Watchstrap bundle is a compact, weather-resistant interval timer with loud beep and vibration, paired with a secure watch-style strap for hands-free timing during runs and workouts.

If you train outdoors, coach classes, or want a simple, reliable way to track rounds and rest intervals without pulling out a phone, this Gymboss bundle gives you a rugged, easy-to-read interval timer plus a breathable watch strap that converts the timer into a wrist-worn device. The PLUS model increases moisture resistance and volume, while the strap transmits vibration directly to your wrist so you never miss a cue.

How does this timer perform in rainy or sweaty outdoor workouts?

The Gymboss PLUS model was designed with increased water resistance and sweat tolerance so it continues to operate outdoors in light rain or during intense sweating. Its hard-wearing case and impact-resistant build help protect internal components from typical outdoor stresses.

• Improved moisture resistance for outdoor use
• Sweat- and impact-resistant housing
• Loud beep plus vibration for audible and tactile alerts
• Compact pager-sized design fits on belt or strap

What interval and timing options can I set?

Program one or two intervals between 2 seconds and 99 minutes and let Auto mode repeat them for circuit-style sessions. You also get a built-in stopwatch and clock for warm-ups, cooldowns, or event timing.

• Single or dual-interval programming
• Interval range: 2 seconds to 99 minutes
• Stopwatch and clock functions included
• Adjustable alarm duration and vibrate-only mode

How will the watch strap change how I use the Gymboss?

The included watch strap converts any Gymboss with a removable belt clip into a comfortable wrist timer, keeping alerts close to your body so vibrations are easily felt. The strap’s perforated design improves airflow during long runs and the stainless hardware secures the timer in place.

• Secure snap-in attachment for removable-clip Gymboss models
• Perforated band for breathability and comfort
• Black stainless hardware for durability and low profile
• Vibration transmits directly to the wrist for reliable cues

What power and sizing details should I expect?

The Gymboss PLUS is powered by a single AAA battery (not included) and measures roughly 55 x 44 x 14 mm—about the size of a small pager—so it stays unobtrusive whether clipped to gear or strapped to your wrist. The alarm can be set to different durations and silenced in favor of vibration when discretion is needed.

• Dimensions: ~55mm x 44mm x 14mm (2.25 x 1.75 x 0.5 in)
• Powers on one AAA battery (user-supplied)
• Alarm durations: 1, 2, 5, or 9 seconds; vibrate-only option
• Includes removable belt clip and quick-attach strap

Who is this for? If you’re an outdoor runner, group-class instructor, or anyone who prefers a small, dependable interval timer over a phone app, the Gymboss Plus Interval Timer and Watchstrap bundle offers a weather-tolerant, tactile timing solution. It’s ideal for coaches who need quick stopwatch access, athletes who benefit from wrist vibrations during sprints and intervals, and fitness enthusiasts who want a compact, standalone timer that won’t distract from training.
