Rogbid SpinR: a $50 smartwatch with a mouse-style scroll wheel and a 100-day battery

Rogbid has launched the SpinR, a rugged budget smartwatch priced at $49.99 that puts a gaming-mouse-style optical scroll wheel on the side of a 51mm case. The 1,100 mAh battery — unusually large for a wrist-worn device — earns a manufacturer claim of 100 days of standby life, dwarfing the 300–500 mAh packs found in most rivals. For anyone frustrated by constantly charging their watch, that headline number alone will turn heads.

The scroll wheel

The SpinR's party trick is a photoelectric rotary knob built into the case edge. Rather than a standard digital crown or a rotating bezel, it uses an optical sensor — the same principle as the one underneath a gaming mouse — to read how far you've turned it and translate that into menu navigation. The practical upside is real: scrolling through notifications with wet hands or work gloves is far easier than swiping a small touchscreen. Whether the mechanism holds up over months of daily use is something only long-term testing can answer, and no independent review has run that test yet.

The specs

The 1.7-inch LCD runs at 360×360 pixels — sharp enough to read notifications in direct sunlight, per Notebookcheck (July 2026). The case measures 13mm thick, so this isn't a slim everyday watch. Water resistance is rated IPX8 (up to 30 meters), making it fine for rain and swimming but not scuba diving. An HX3918 optical sensor handles heart rate. Storage is a tight 128MB — enough for watch faces and basic apps, not a music library. Bluetooth 5.4 keeps the connection stable. There is no onboard GPS; the watch borrows location data from your phone.

Where it fits — and where it doesn't

At $49.99, the SpinR undercuts most branded competition. The Samsung Galaxy Fit 3 costs around $60 and offers a 13-day real-world battery; the Amazfit Bip 6 runs closer to $80 with a 14-day AMOLED display. The SpinR's standby claim of 100 days is a manufacturer figure under ideal conditions — active use with sensors running will cut that significantly. The TechRadar budget smartwatch roundup notes that GPS-equipped options like the Amazfit Active 2 ($99) dominate the affordable segment for runners and cyclists, which puts the SpinR firmly in the "long-lasting basic tracker" category rather than a sports companion.

The watch is available now directly from the Rogbid Official Store in Tech Black and Vibrant Orange. No major US or UK retail partners — Amazon, Best Buy, Argos — have listed it yet, so factor in international shipping if you order.
