NH35 Automatic vs. VH31 Quartz: Which Movement Is Right for You?

Both the NH35 and VH31 are popular choices in custom watches, but they offer very different experiences. Here’s a side‑by‑side breakdown to help customers understand the strengths of each.

Overview

  • NH35 Automatic — A mechanical, self‑winding movement known for durability, reliability, and long‑term serviceability.

  • VH31 Quartz — A battery‑powered quartz movement with a smooth 4‑tick‑per‑second sweep that mimics the look of an automatic.

How They Work

NH35 Automatic

  • Powered by a mainspring and rotor

  • Winds itself as you move

  • No battery required

  • Fully mechanical with 24 jewels

VH31 Quartz

  • Powered by a battery

  • Uses quartz regulation for accuracy

  • “Sweeping” seconds hand ticks 4 times per second

  • Low maintenance and lightweight

Accuracy

  • NH35: Typically −20 to +40 seconds per day (can be regulated tighter)

  • VH31: Extremely accurate at around ±15 seconds per month

If precision is the priority, quartz wins. If mechanical charm matters more, the NH35 is the classic choice.

Maintenance

NH35

  • May need servicing every 4–7 years

  • Can be regulated and repaired

  • Built for long‑term use

VH31

  • No servicing required

  • Battery replacement every 2–3 years

  • Not designed for mechanical repair


Feel & Experience

NH35 Automatic

  • Smooth mechanical sweep

  • Weightier, more traditional wrist feel

  • Appreciated by enthusiasts

  • Transparent casebacks showcase the movement beautifully

VH31 Quartz

  • Lightweight and slim

  • Sweep mimics an automatic without the cost

  • Great for everyday wear

  • Perfect for customers who want the look without the upkeep

Durability & Reliability

  • NH35: Extremely robust; proven in divers and field watches

  • VH31: Highly reliable; fewer moving parts mean fewer failure points

Both are dependable — the difference is in how they achieve it.

Cost

  • NH35: More expensive due to mechanical complexity

  • VH31: More affordable, making it ideal for budget‑friendly builds

Which One Should You Choose?

Choose NH35 Automatic if you want:

  • A true mechanical watch

  • No battery changes

  • A movement you can regulate and service

  • A premium feel and visible movement

Choose VH31 Quartz if you want:

  • High accuracy

  • Low maintenance

  • A smooth sweep without the cost of an automatic

  • A lightweight, everyday‑ready watch
