A rectangular lozenge case in pale gold PVD paired with a mesh-link bracelet of the same tone, the Series 21 sits in the space between fashion jewellery and fitness tracker. At 25mm wide it is built for smaller wrists, and the sliding clasp means fit can be dialled in without removing links. The smart module connects to the Radley Active App via Bluetooth and runs for up to five days between charges. Step counting and a wrist-based heart rate monitor underpin fourteen sports-tracking modes, alongside sleep tracking, hydration reminders, and the ability to receive phone notifications and control music remotely. The touchscreen serves as the dial, with swappable watch faces including custom photographs — the backlight handles low-light reading in place of any luminescent coating.

Learn more about Radley
Radley London was founded in 1998 as a handbag brand, and named for the founder's Scottish terrier. The dog became the logo, and remains the single most recognisable thing about the label — stamped, embossed, or hanging from a bag as a leather charm.
The watches are licensed rather than manufactured in-house, produced by a specialist watch maker under agreement and sold through the same department stores and jewellers as the bags.
They are designed as accessories to the accessories: slim cases, printed or textured dials, coloured leather straps, and the terrier appearing on the dial, the caseback or the strap keeper. Quartz movements, gift-market pricing.
Radley is a well-run British accessories brand and its watches are exactly what the label suggests they are — coordinated, characterful and inexpensive, rather than horological.

Frequently asked questions, and things you should know about this watch
Will the glass scratch?
It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.
Sapphire, mineral and acrylic comparedDoes it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedWhat size strap does it take?
16mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as women's.
