Graf Zeppelin LZ126 Los Angeles 8644-5 Pulsometer Watch

Graf Zeppelin LZ126 Los Angeles Pulsometer

The Graf Zeppelin LZ126 Los Angeles 8644-5 is a quartz pulsometer watch designed for medical professionals who need to determine heart and pulse rates quickly. Its specially calibrated tachymeter scale performs this measurement directly on the wrist. The 42.00 mm stainless steel case houses a beige dial with numeric markers and a date window. A brown leather strap with a buckle clasp secures the timepiece.

Suited for clinical use; not for diving

This watch suits doctors, nurses, and paramedics who require a dedicated tool for patient vital checks during examinations. The 50 m water resistance handles hand washing and rain but excludes swimming, diving, or high-pressure water exposure. Buyers needing a watch for aquatic sports or deeper immersion should look at models with higher water-resistance ratings.

Swiss Ronda 6203.B calibre quartz movement

The watch runs on the Swiss-made Ronda 6203.B calibre, built to extend battery life while delivering high precision. This movement choice supports the pulsometer function with reliable timekeeping essential for accurate rate calculations. Mineral crystal protects the dial from daily scratches in clinical environments.
