Gymboss Interval Timer & Stopwatch — Plus Black/Green Softcoat, Vibration & Water-Resistant

Gymboss Plus Interval Timer and Stopwatch in Black/Green Softcoat is a compact, durable interval timer that tracks one or two intervals, repeats automatically, and notifies you with chime and vibration for workouts and outdoor training.

The Gymboss Plus combines a stopwatch, clock and programmable interval timer in a pager-sized unit designed for athletes, trainers and outdoor enthusiasts. Its enhanced water resistance, loud beep, and vibration mode make it practical for group classes, rain-prone sessions, or noisy training environments. The device’s straightforward controls and removable belt clip let you focus on the session instead of fiddling with complicated menus.

How precise and flexible is the interval timing?

The Gymboss Plus times either one or two intervals with settings from 2 seconds up to 99 minutes, and can repeat sequences up to 99 times in Auto mode. You can toggle between chime and vibration alerts or use both, and set alarm duration for one, two, five, or nine seconds.

• Intervals adjustable between 2 seconds and 99 minutes
• Supports one or two-interval programming for simple and complex sets
• Auto-repeat up to 99 cycles for long workouts or circuits
• Alarm duration choices: 1, 2, 5, or 9 seconds

Can I hear or feel the alert during group classes or outdoors?

The unit includes a very loud beep suited to group settings or outdoor training where ambient noise is high. If sound is disruptive, you can reduce beep volume or switch to vibration-only mode for discreet notifications.

• High-decibel beep for clear audio cues in noisy environments
• Vibration mode for silent interval alerts
• Option to dim or silence the beep while keeping vibration active

Is the Gymboss Plus built to handle sweat and wet conditions?

This model has improved water resistance and is both sweat- and impact-resistant, making it a solid option for outdoor runs, veteran training, and humid gym sessions. It’s not a dive instrument, but it tolerates rain and moisture exposure better than basic timers.

• Increased water resistance for rainy or sweaty conditions
• Sweat- and impact-resistant housing for active use
• Softcoat finish improves grip and comfort during wear

How portable and easy to use is it day to day?

About the size of a small pager, the Gymboss Plus is powered by a single AAA battery (not included) and includes a secure removable belt clip. The simple interface focuses on core functions—clock, stopwatch, and interval timing—so setup is quick and reliable without a steep learning curve.

• Compact dimensions: 2.25 x 1.75 x 0.5 inches (55 x 44 x 14 mm)
• Comes with a removable, secure belt clip for hands-free wear
• Uses one AAA battery for easy replacement and long runtime

Who is this for? The Gymboss Plus Interval Timer and Stopwatch suits athletes, personal trainers, group instructors, and outdoor exercisers who need a reliable, no-nonsense timing tool. If you want a rugged, portable timer with audible and vibration alerts, straightforward programming for single- or dual-interval workouts, and a compact design that clips onto clothing or gear, the Gymboss Plus is built to deliver consistent cues in noisy or wet settings.
