Smart ring platform VW-R1
A screenless Grade-5 titanium ring for sleep and recovery tracking. Sensing runs continuously and syncs to a companion app, which keeps the form factor discreet enough to wear overnight — and makes it the platform for buyers whose product promise is sleep, not steps.
- Grade-5 titanium outer shell with PVD finishing — no plastic in the visible body
- Continuous PPG, skin temperature and motion, all app-side with no display to power
- Sizing kit available so you can fit customers before shipping inventory
- Companion app, packaging and finishes carry your brand

Figures shown are the standard configuration used for quotation. Confirmed values are stated in your written quotation and frozen at golden-sample approval.
Five levels of change, and what each one costs you in time.
On a ring, finish is the product. L2 carries more of the perceived value here than on any other platform in our range.
| Level | What changes | Tooling | Added lead time |
|---|---|---|---|
| L1 · Branding only | Laser marking inside the ring, your app name and icon, your retail box and quick-start guide. Runs on existing tooling. | None | +0 days |
| L2 · Finish & surface | Black, gold or rose-gold PVD, brushed or matte surface, inner coating specification. | Modified tooling | +7–15 days |
| L3 · Sensor configuration | Add SpO₂ or extra optical channels on the standard board, including firmware and algorithm integration. | None (board-level) | +10–20 days |
| L4 · New industrial design | A new outer profile, width or thickness built from your ID drawings, with a full validation cycle and new sizing tooling. | New tooling (per size) | +35–50 days |
| L5 · Full ODM programme | We take the product from specification through certification to mass production — firmware, companion app, sizing kit, packaging and compliance documentation included. | New tooling | Programme schedule |
Added lead time is measured on top of the standard 25–35 day production window and starts from approval of the change, not from enquiry. New tooling on a ring is per size, not per model — budget for the whole size range if you go to L4.
Three typical builds off the same platform.
These are the configurations most buyers ask for. They are starting points for a quotation, not a fixed catalogue — a build can combine options across rows.
| Reference | Configuration | Suited to |

- USB-C charging case
- Quick-start guide in your language
- Neutral outer carton, mixed sizes as declared
Sizing kit
- Reusable set covering US 6–13, ordered as its own SKU

- Recommended for direct-to-consumer launches; less relevant for retail shelf
Ring size mix is declared per order. A wide mix across the whole range means more tooling allocation than a concentrated mix — send us your expected split with the enquiry.
Certification is a process, not a sticker.
We handle the testing and documentation pathway for the markets you ship to. Which certificates you actually need depends on the destination and on what your product claims.
European Union
Radio Equipment Directive for the Bluetooth radio, with technical file and declaration of conformity.
United States
Equipment authorisation for the radio transmitter, plus the test report the retailer will ask for.
Restricted substances
Applies alongside CE in the EU and is routinely required by retailers elsewhere.
Chemical compliance
Matters more on a ring than on any other platform — the whole product sits against skin, all day.
Also handled for this platform
- UN38.3 test report and MSDS for the cell and the charging case
- Nickel-release and skin-sensitisation test reports for the inner surface
- UKCA where you ship to Great Britain
- Third-party inspection on request (SGS, Bureau Veritas)
