AUPHY Mechanical Metronome M350 — Classic Pyramid Wind-Up Metronome, Accent Bell, 40-208 BPM

The AUPHY M350 is a battery-free, wind-up mechanical metronome that delivers stable tempos from 40 to 208 BPM with selectable accent beats for reliable practice across piano, guitar, drums, violin, saxophone and more.

Built in a traditional pyramid silhouette, the M350 combines a metal clockwork movement and durable POM gears inside a high-strength PC casing with a transparent dust cover. Its lowered center of gravity and tight gear tolerances keep timing accurate (within about 1%), while the mechanical wind-up gives roughly 2,160 clicks per full wind — enough for focused practice without relying on batteries or apps.

How do I set tempo and accent patterns on the M350?

Tempo is selected by sliding the pendulum weight to the tempo marking corresponding to 40–208 BPM. For accented beats use the beat-selection control to choose 2, 3, 4, or 6; set it to 0 to silence the accent bell while keeping the regular ticks.

• Move the pendulum weight to the desired BPM marking.
• Choose beat pattern: 2, 3, 4, 6 for accents or 0 to mute accents.
• Wind the spring fully for longest run time.
• Flick the pendulum to start; use the bottom brake to stop.

What maintenance keeps the metronome accurate and long‑lasting?

The M350’s metal clockwork and POM gear train resist corrosion and wear, but simple care extends lifespan: keep the dust cover closed, avoid over-winding, and store the unit upright on a stable surface. If it needs cleaning, wipe the exterior and dust cover with a soft, dry cloth.

• Close transparent dust cover when not in use to prevent grit build-up.
• Avoid over-winding; stop when resistance increases noticeably.
• Wipe with a dry cloth; don’t use solvents on the gears or movement.
• Store horizontally only during use; otherwise keep upright and secure.

How long will a single wind run at practice tempos?

On a full wind the M350 produces approximately 2,160 mechanical clicks. Actual run time varies with tempo: slower BPMs yield closer to 10–40 minutes per wind, while faster tempos shorten the runtime accordingly.

• Full wind delivers ~2,160 ticks total.
• Lower tempos (40–80 BPM) approach the high end of run time.
• Fast tempos reduce continuous running duration.
• Wind again between practice sets for uninterrupted sessions.

Who is this for? The AUPHY M350 is ideal for students, teachers, and instrumentalists who prefer a tactile, visual tempo guide without electronic dependence. It suits beginners learning steady time and experienced players refining phrasing and accent patterns. Because it’s mechanical, compact, and visually classic, the M350 also fits studios and stage setups where a reliable, battery-free metronome is preferred.
