Vintage Swiss Telemeter Chronograph, Landeron 48, Snail Tachymeter 35mm (No Name)

This vintage Swiss chronograph reflects a period when functionality often came before branding. Like many watches produced between the 1930s and 1950s, it carries no brand name on the dial — a common practice for pieces made for private retailers, export markets, or small distributors. Today, such watches offer collectors an honest and design-focused alternative to logo-driven pieces.

At its core is the well-known Landeron 48 manual-wind chronograph movement, one of the most widely used Swiss calibers of its era. Reliable and historically important, the Landeron 48 adds mechanical credibility and makes this vintage Swiss chronograph especially appealing to collectors who value traditional column-wheel-era alternatives and cam-operated chronograph development.

What immediately stands out is the detailed dial, featuring both a telemeter scale and a snail tachymeter scale. The telemeter measures distance based on the time between a visible event and its sound, while the spiral “snail” tachymeter allows for average speed calculations over extended intervals. Together, these scales reflect a time when chronographs were appreciated as practical instruments, not just stylistic elements.
