TOPsic Compatible Vivosmart HR Strap, Soft Silicone Replacement Accessories Adjustable Wristband Watch Straps Designed for Vivosmart HR Smart Watch,Not for Vivosmart HR+

Very easy to put on. Perfect fit

Second replacement for this watch. Easy to fit. Looks good. Screwdrivers supplied. One star off for cross head screws rather than hex fitting.

One side of the strap fits fine, the other (button) side, not at all as the 4VB... series clearly requires more room for the mounting than the strap was designed for. There are no elements of the watch case which could be removed to make it fit - it's hard moulded plastic and all part of the main case.

It appeared to fit initially ok but when I tried to use different functions of the watch it was clear that the watch's button was being permanently depressed by the strap. I tried refitting it several times and eventually gave up. Reverted back to old broken strap :-(I'm aware there are slight variations between Vivosmart HR versions that can be differentiated by the first characters of the serial number.My watch serial number is commencing 4VB...

I have a Gamin - works well, changed the strap once, all good. I THOUGHT that I had found an extra-long strap, bought it, and found not - oh well, held onto it as does fit and [only just] fits my wrist + the earlier one is going strong. We live and learn!

For the money this is a great replacement strap.Fits perfectly and easy to fit, looks god and has resurrected a watch that has been laid in a drawer for ages.Highly recommended!
