Watch Reviews: Every Term Explained

The Language of Watch Reviews

Watch reviews use specific terms that can confuse newcomers. Here is what they actually mean.

Case Terms

• Lug-to-lug: total length from tip of top lugs to tip of bottom lugs — the most important measurement for fit
• Bezel diameter: width across the bezel — usually the number quoted as "case size"
• Crystal diameter: width across the crystal — smaller than bezel diameter
• Thickness: height from caseback to crystal top

Movement Terms

• Beat rate: oscillation frequency — 21,600 vph (6 beats/sec) or 28,800 vph (8 beats/sec)
• Amplitude: how far the balance wheel swings — healthy range is 270-310 degrees
• Beat error: asymmetry in the tick-tock rhythm — should be under 0.5ms

Quality Terms

• Finishing: surface treatment of case, dial and movement — brushing, polishing, engraving
• Applied indices: physical markers glued/riveted to dial — premium over printed
• AR coating: anti-reflective coating on crystal — improves clarity

Frequently Asked Questions

What does "proportional" mean in reviews?
The watch's dimensions work together — no single element (bezel, lugs, crown) looks oversized or undersized relative to others.

What is "wrist presence"?
How the watch looks and feels on the wrist — a combination of size, weight, finishing and design impact.
