I wanted a spy gadget watch as a kid. Somehow I ended up building the tool that builds it.

ALPHA FIELDMASTER - Spy Watch is the full instrument behind the ALPHA FIELDMASTER - Tactical Chrono face. Analog chronometer outside, field system inside. THE FRONT — A working analog chronometer with metal skeleton hands, lume markers, a live seconds perimeter, heart rate, watch battery, steps and automatic status alerts. Tap the dial to roll through three fronts: the plain chronometer, EXT mode with Garmin Body Battery and stress level rails, and the sleep dial at full brightness. Lower your wrist and the sleep dial dims in from whichever front you were on; raise it and your front comes back. THE GATE — Swipe up to reach the fingerprint access gate. Hold to verify, watch the scan complete, and the Field System opens. THE FIELD SYSTEM — Four sensor-driven tools live behind the gate: • RADAR — detects nearby Bluetooth devices and places confirmed signal bearings on a compass as you turn your wrist. • TAILSCAN — mark the signals around you, move, and see which ones are still with you. • SEISMIC — uses the accelerometer to visualize vibration through a surface. • DEAD DROP — plant a GPS position, move away and navigate back to it. SIGNAL INTEL adds a live ledger of nearby Bluetooth contacts with broadcast name, manufacturer or category, signal strength and trend. Strong signals can be analyzed through the HACK flow to earn Field Charge, the in-app energy used by the modules. Every reading comes from the watch or a detected signal. If the hardware cannot establish an answer, FIELDMASTER says so instead of inventing one. No account. No companion phone app. Nothing leaves the watch. Built for 43 Garmin AMOLED watches, with native full-screen artwork for every display size.
