How to Use Heat Gun for Watch Aging: Temperature Guide

Why Use a Heat Gun?

A heat gun gives you more control than an oven. You can target specific areas and adjust temperature in real-time. This is the preferred method for many experienced builders.

Temperature Settings

• 200-250F: Light yellowing of lume. Minimal effect on paint.
• 250-300F: Moderate yellowing. Slight darkening of dial.
• 300-350F: Heavy yellowing. Noticeable color change.
• 350-400F: Aggressive aging. Risk of paint damage.

Techniques

Lume Yellowing

Hold heat gun 6-8 inches away on low setting. Move constantly over lume areas. Check every 30 seconds. Stop when desired yellow is reached.

Dial Darkening

Hold heat gun 8-10 inches away. Move in slow circles. The dial will darken gradually. This takes 5-10 minutes.

Bezel Pip

Focus heat directly on the pip. Hold 4-6 inches away. The pip will darken quickly. Check every 10 seconds.

Safety

• Work in ventilated area
• Wear heat-resistant gloves
• Keep flammable materials away
• Start with lowest temperature

FAQ

Can I use a hair dryer instead?

Hair dryers do not get hot enough. You need a proper heat gun for thermal aging.
