F73 Screenless Smart Band with 7g Featherlight Head, 110mAh Battery and 36 App Languages

Product Name: F73 Screenless Smart Band

Product Overview: The F73 is a screenless smart band built for buyers who want health tracking without a screen — and without the weight. Its head weighs just 7g and the whole band 14g, the lightest in its family, on a soft fabric strap with a gold-tone monitor. With no display to power, the 110mAh battery runs 15–20 days under typical use and 10–12 days under heavy use. HRV monitoring, red-light blood oxygen tracking, five heart rate zones, sleep monitoring and women’s health cover the essentials, all viewed in the Joeme Fit app in 36 languages. Five fabric colours — cherry blossom pink, bamboo green, sky blue, jet black and mountain mist grey — fit different buyers.

Sourcing Notes: The Chinese and English spec sheets are identical. The F73 is a screenless band, not a watch, so it is listed under Smart Bracelet (E910/F360/F370 precedent). Unlike the F360 and F370, the F73 spec sheet lists NO ECG, so no ECG is stated here; it also lists no sports modes, so none are claimed even though the detail images mention multi-sport mode. Health claims are deliberately limited for overseas listing, following the Q520/E910 precedent: non-invasive blood glucose monitoring, blood pressure monitoring and body temperature monitoring are in the spec sheet but are NOT stated here. Weight and battery life follow the spec sheet (7g head / 14g total; 15–20 days typical, 10–12 days heavy); one detail image says 15g and the detail-page spec table says 7–15 days with iOS 9.0+/Android 4.4+, and neither is used. The heart rate sensor is TYHX3602 per the spec sheet (the detail-page table shortens it to HX3602). Colours follow the spec sheet (5 colours); the detail page shows silver and gold monitor options, and the white-background images are all gold. Strap size (225mm, 22mm) appears only in the detail page and is not claimed.
