Junghans Meister Telemeter - 40mm - Black

The telemeter scale allows you to measure distance based on the time elapsed between seeing an event and hearing it. For example, you can estimate the distance of a storm by timing the interval between seeing lightning and hearing thunder.

The tachymeter scale is used to calculate speed. For instance, start the chronograph when you begin a measured mile (or kilometer). When you complete the mile, stop the chronograph. The number on the tachymeter scale indicated by the second hand is your average speed in miles (or kilometers) per hour.

Water resistance ratings vary by specific model. Generally, this watch is designed for everyday wear and should be protected from submersion in water unless it has a specific high water resistance rating. Refer to your watch's manual for its exact water resistance specifications.

It is generally recommended to have a mechanical watch serviced every 3-5 years to ensure optimal performance and longevity of the movement. This includes cleaning, lubrication, and adjustment.

The 'Meister' designation in Junghans watches typically indicates models that represent the pinnacle of the brand's watchmaking heritage and design philosophy, often featuring classic aesthetics and refined movements.

Unless your specific model has a high water resistance rating (e.g., 100 meters or more) and is explicitly stated as suitable for swimming, it is best to avoid wearing it during water-intensive activities like swimming or showering to protect the movement and seals.

Ensure the chronograph has been fully reset to zero before starting. Operate the pushers firmly but gently. If the issue persists, it may require professional servicing.

Mechanical watches can be affected by magnetism or require servicing. If significant time deviation occurs daily, consult a qualified watchmaker.

Wind the crown until you feel firm resistance. Do not force it past this point. If winding feels gritty or impossible, the movement may need attention.
