X-Ray Blood Hourglass

A watch face like nothing else on your wrist: a photoreal X-ray of the arteries beneath your band, with the time rendered in dripping blood inside the corridor between your forearm bones. It's alive. A blood reservoir fills through the hour like an hourglass and drains at the top of the next; droplets fall from the digits and splatter on the surface; move your wrist and the pool sloshes. A realistic anatomical heart beats at your live heart rate. Tap the face for readouts drawn from your own body — a 7-day step chart, a 24-hour heart-rate trace, blood-oxygen history — or drain the reservoir to reveal the vessels beneath. Built for AMOLED fēnix-class watches, with a burn-in-safe always-on view that keeps a dim blood clock glowing through the night. Every pixel is baked art, composited live — a true statement piece.

08/04/2026 - Fixes a crash (IQ! icon) on Vivoactive 5 and Approach S50, with rendering now matched to the fēnix 8. Six devices that cannot support the face's graphics were removed from compatibility.
