Caviar launches $13,000 iPhone 17 Pro featuring a built-in Geiger counter

Caviar has launched the "Geiger," a custom iPhone 17 Pro featuring a fully functional built-in Geiger counter. The luxury modification company embedded a physical SIG-RM1208 dosimeter watch into the back of the device, allowing users to monitor gamma radiation levels in their immediate environment.

Priced starting at $13,130 for the base 256GB iPhone 17 Pro, the Geiger replaces Apple's standard glass back with a heavy-duty titanium shell. The design draws heavy inspiration from high-precision industrial equipment, using exposed screws, thick metal panels, and a red indicator line running down the center axis. A sculpted radiation hazard symbol sits near the bottom of the case, directly indicating the purpose of the built-in module.

The central watch module is a legitimate Geiger-Müller counter rather than a software trick or companion app. It features a small digital screen that displays real-time radiation readings and can be configured to sound a warning beep if radiation exceeds a preset threshold. Surrounding the digital readout is a traditional analog watch face, driven by a Swiss Ronda 763 quartz movement to track the time.

The integration of a physical watch mechanism and heavy titanium casing adds significant bulk, making the customized smartphone noticeably thicker and heavier than a standard iPhone. The Geiger is highly exclusive, with production strictly limited to seven total units.

Each device will include its specific production number engraved on the chassis and ship with a personalized certificate of authenticity. Buyers can also opt for higher storage configurations or the larger iPhone 17 Pro Max model at an increased cost.
