Replacement straps for the 19mm ID205 family of watches, sold under names like Octandra, Fitpolo, Willful, Letsfit, LETSCOM, YAMAY and GRV: soft silicone sport bands or a braided nylon loop, in singles or 2-packs.
These bands fit one of the most common budget watch designs: the ID205 family. The same square body has been sold under many brand names, and all of them share a 19mm strap width, which is what makes a replacement band like this so easy to find.
Start by identifying your watch. Look for the model code on the case back, in the manual or on the device screen inside the app. Look for:
Many brands use these codes. The fit lists name Octandra, Fitpolo, GRV FC1, Willful, Letsfit, LETSCOM, YAMAY SW020, SW021 and SW023, Lintelek, Blackview SW01 and SW02, and HAFURY. The OCTANDRA Move is one of them: its model number is ID205L.
If there is no code in sight, measure the gap between the lugs where the strap meets the case. A reading of 19mm confirms the width. Most bands of this type attach with standard 19mm spring bars, so any 19mm strap with the same bar style will clip on.
Getting the fit right matters more than the colour. A strap that is a millimetre too narrow rattles and pulls against the pins; one that is too wide will not seat at all. Take a minute to check, and the new band stays secure through every workout.
The bands guide covers the wider 22mm size as well, with tips on measuring lugs.

Silicone is the workhorse. It shrugs off sweat, rinses clean under the tap and stays comfortable through the night, which keeps sleep tracking going. Choose it for runs, gym sessions and wet walks.
Braided nylon is the comfort pick. It breathes on hot days, adjusts to any point rather than to fixed holes, and feels softer against the skin for all-day wear. The Relting pair comes in beige and dark pink and also fits the Casio W-71 and W-86.
Match the band to the habit:
Colour is a motivator too. A bright band on the gym bag hook is a visual cue to train, and a neutral one blends in at work, so owning one of each helps the watch fit every part of the day.
The OUTPUTBT strap measures 4.8 inches and weighs 0.71 ounces, a typical size for the stock band on these watches.
Changing a 19mm band is a quick job, and quick-release versions make it quicker still. Clear a small space on a table and lay a soft cloth down so the watch face does not get scratched.
For bands with standard spring bars:
If a spring bar flies off across the room, search slowly with a torch held low to the floor; the bars are tiny but catch the light. Working over a tray or a towel avoids the hunt altogether.
Quick-release straps, like the braided nylon pair, have a small lever on the bar. Slide the lever, and the bar retracts without tools.
A few habits keep straps lasting:
While the watch is off, wipe the back and the two charging dots. The ID205L family charges on a 2.84mm magnetic cable, and clean contacts help it charge first time. A spare lives on the 2.84mm charging cable page.
A 19mm band only makes sense for a 19mm watch, so the real comparison is with the other strap sizes that FitPro-style watches use. Knowing the neighbours helps avoid ordering the wrong one.
If your lug gap measures 22mm, head to the 22mm silicone sport bands or the 22mm nylon loops instead.
A short checklist before ordering a 19mm band:
Straps also make a thoughtful low-key gift for anyone who already owns an ID205L watch. Check the model code on their watch first, then pick a material that suits how they spend the day.
Nothing refreshes an older watch for less money than a new band, and a watch that feels good gets worn. Worn every day, it keeps counting steps, logging sleep and building the streak you started with.
For owners with an ID205L watch that has stopped charging or turning on, the not-working fixes are worth a look before replacing anything else.
