 However, positioned on the lower sector, the dial has been equipped with an arc-shaped mechanical thermometer, adding immediate distinction to this model. Enabled entirely by mechanical means, the thermometer, which is capable of indications from      -35°C to 45°C, uses a proprietary module built into the base movement, and its impressive accuracy is achieved via a bimetallic coil.
