Tissot Telemeter 1938 Watch - Silver - 42mm

It is powered by a Swiss automatic movement, meaning it winds itself through the motion of the wearer's wrist.

The tachymeter scale is used to measure speed over a known distance. The telemeter scale is used to measure distance based on the time between seeing an event (like lightning) and hearing it (like thunder).

While the watch may have a degree of water resistance, it is a luxury timepiece. It is not recommended for swimming or prolonged immersion in water unless specifically rated for such activities.

This watch uses an automatic mechanical movement, not a quartz movement, so it does not have a battery that needs replacement.

The strap is made of brown leather with contrasting cream stitching and features a stainless steel double folding clasp for secure and comfortable wear.

The case diameter is 42mm.

Yes, the Tissot Telemeter 1938 watch includes a date function.

Ensure the watch has been sufficiently wound. If automatic, wear it consistently for at least 8-10 hours a day. If manual winding, wind it fully. If the issue persists, the movement may require servicing.

Ensure you are not setting the date between 9 PM and 3 AM, as this can interfere with the date-changing mechanism. Set the time to midday before adjusting the date.

This indicates a potential seal failure and water ingress. Remove the watch immediately and take it to a qualified watchmaker for inspection and repair to prevent further damage.

Do not force the crown. There may be debris or a minor misalignment. Take it to a watchmaker for professional assessment.
