Gymboss interval timer and watchstrap bundle, Black w/ Blue Buttons, One Size Fits All — dual intervals, vibration & chime

The Gymboss Interval Timer and Watchstrap bundle is a compact, repeatable interval timer plus a breathable watch strap that snaps your Gymboss into place so you can time workouts hands-free.

Whether you train HIIT, run intervals, coach classes, or use a stopwatch for drills, this two-piece bundle combines the small-but-powerful Gymboss interval timer with a purpose-built strap that converts it into a wrist-worn timer. The timer handles single or dual intervals with audible chime and vibration alerts, while the strap secures the unit to the wrist so you feel every buzz without interfering with movement.

How precise is the Gymboss for interval training?

The Gymboss times intervals from 2 seconds up to 99 minutes and can repeat them automatically up to 99 cycles, so it covers everything from sprint repeats to long sets. You get both chime and vibration cues and selectable alarm durations to suit noisy gyms or quiet environments.

• Two configurable intervals for varied work/rest schemes
• Interval length: 2 seconds to 99 minutes
• Repeat up to 99 times in Auto mode
• Alarm options: chime and vibration; 1, 2, 5, or 9 second duration

Can I use the Gymboss as a regular stopwatch and clock?

Yes — in addition to interval timing, the unit includes a built-in stopwatch and a clock display so it functions as a small multi-purpose timing device. The compact form factor fits in pockets, clips to a belt, or docks into the included watch strap for wrist use.

• Stopwatch mode for lap and drill timing
• Simple clock display for everyday use
• Secure removable belt-clip included for alternative carry

How does the watch strap improve usability during exercise?

The high-quality perforated strap snaps the Gymboss timer into place so the vibrating alarm transfers directly to your wrist, making alerts easier to notice during movement. The band breathes to reduce sweat build-up and uses black stainless steel hardware for durability and a clean look.

• Quick, secure snap fit for Gymboss models with removable clips
• Perforated strap for breathability during intense sessions
• Black stainless steel hardware for strength and corrosion resistance

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

The timer is about the size of a small pager and is designed to resist sweat and impact for active use. It runs on one AAA battery (not included) and measures approximately 2.25 x 1.75 x 0.5 inches (55 x 44 x 14 mm), making it unobtrusive whether worn on the wrist or clipped to gear.

• Compact dimensions: 55mm x 44mm x 14mm
• Pocketable, sweat- and impact-resistant housing
• Powered by one AAA battery (battery not included)

Who is this bundle for? If you need a reliable, easy-to-program interval timer that you can wear on your wrist, the Gymboss timer plus watch strap is ideal for runners, circuit trainers, coaches, and anyone who prefers tactile vibration alerts over screen-based timers. It suits athletes who switch between clipping the device to clothing and wearing it on the wrist, and coaches or fitness professionals who want a durable, repeatable timing tool for classes and drills. This bundle keeps timing simple: set intervals, feel the vibration, and focus on the workout.
