2. In-Depth Comparison

Movement & Performance

This is the most significant difference between the two models, representing two distinct philosophies of timekeeping:

• ADDIESDIVE 41mm Automatic (NH35): This watch is powered by the popular Japanese Seiko NH35 caliber. It is a true mechanical, self-winding movement with a sweeping second hand (6 ticks per second) that provides the classic soul of traditional watchmaking. It features hacking (the second hand stops when setting the time) and hand-winding capability, but its accuracy is generally less than quartz (typically $\pm 15$ to $40$ seconds per day). It requires no battery but must be worn or manually wound to maintain its 41-hour power reserve.
• ADDIESDIVE AD2030 Quartz (VH31): This watch uses the Seiko VH31 quartz movement, which is often referred to as a "mecha-quartz" because it operates on a battery but drives the second hand to tick 4 times per second. This offers a smoother sweep than typical quartz watches (which tick once per second) while maintaining the superior accuracy of quartz (typically $\pm 15$ seconds per month). It is highly reliable, low-maintenance, and much thinner, but it does require a battery change every few years.

Case, Crystal, and Durability

The two watches cater to different durability requirements and aesthetics.

• ADDIESDIVE 41mm Mechanical: This is built as a genuine tool watch. It features a larger 41mm diameter, a high-grade Sapphire Crystal (which is significantly more scratch-resistant than mineral glass), a screw-down crown, and a 200m water resistance rating, making it suitable for professional diving.
• ADDIESDIVE AD2030 Quartz: This is a dressier, smaller watch at 36mm, a size favored for classic and vintage styles, and excellent for smaller wrists. The crystal is a domed K1 Mineral Glass. While visually appealing and contributing to the vintage look, it is much more susceptible to scratches than sapphire. The 100m water resistance is robust for swimming and water sports but is not rated for serious saturation diving.

Unique Features

ADDIESDIVE 41mm Automatic	ADDIESDIVE AD2030 Quartz
Unidirectional Bezel: Essential for dive timing.	Sweep-Second Quartz: The VH31 movement gives the look of a mechanical watch with quartz accuracy.
Superior Lume: Uses Swiss BGW9 super luminous material for excellent visibility in dark conditions.	No Lume: A clean, dressier aesthetic, but lacks utility in darkness.
Sapphire Crystal: Offers maximum scratch resistance.	No Logo/Clean Dial: The "No Logo" aspect is a key feature for enthusiasts who prefer a minimalist, sterile dial.

Pros and Cons
