Known for its luxury smartphone modifications, Caviar has added another extraordinary design to its collection. Introduced under the company’s “Grand Complications” collection, the Geiger model stands out with its functional Geiger-Müller counter and Swiss-system analog-digital clock integrated into the iPhone body. Capable of monitoring ambient gamma radiation levels in real time, the device is positioned as both a luxury accessory and a working radiation measuring tool.

Dosimeter Working on the Rear Panel: SIG-RM1208

At the heart of this specially designed iPhone 17 Pro Max-based model is the SIG-RM1208 dosimeter clock located in the center of the rear cover. The device is not merely a visual design element; Thanks to its Geiger-Müller tube, it precisely measures ambient gamma radiation levels. The obtained micro-sievert (µSv/h) values ​​are displayed on the digital screen of the watch dial, and the system alerts the user audibly and visually when the set safety threshold is exceeded.

On the time measurement side of the dosimeter, a Swiss-made Ronda 763 quartz mechanism is used. Thanks to this, the device functions as an analog clock and a precise measurement station, independent of the smartphone’s own clock.

Industrial Design and Protective Details

The model’s outer casing reflects the aesthetics of professional radiation monitoring devices and industrial laboratory equipment. The prominent design details on the body are listed as follows:

• Brushed Metal Panels: Solid metal armor and visible industrial screws that add durability to the body.
• Technical Lines and Warning Stripes: Red indicator lines running along the vertical axis of the device.
• Embossed Radiation Icon: Three-dimensional radiation hazard symbol engraved on the bottom.
• Limited Production Number: Serial number and certificate of authenticity engraved on the body for each device.

An Extraordinary Meeting of Luxury and Engineering

Shaped around the idea of ​​transforming invisible environmental factors into measurable information, the Geiger concept offers a functional engineering approach rarely seen in the luxury segment. With this model, Caviar elevates standard smartphone usage to the level of a collectible instrument. The limited-edition model is sold in a special blue leather-covered and gold-detailed Caviar Royal gift box.
