In-Depth Comparison

1. Materials and Durability

22mm Seagull Watch Men's Watch Women's Original Strap Bracelet Butterfly Buckle Strap Watch Accessories

The Seagull-branded options are often crafted for a sophisticated aesthetic, with the primary materials being genuine leather and 316L stainless steel. The leather options, which pair well with Seagull's popular dress and chronograph models (like the 1963), offer comfort and a classic look. Stainless steel versions (including Milanese mesh) provide durability and a sleek, modern finish. While the steel is robust, the leather options are not designed for harsh or wet conditions.

The STEELDIVE line is explicitly built for tool watches and dive watch use. The most common and popular strap option is a highly durable, multi-colored rubber band. This material is ideal for water resistance, comfort, and enduring high-intensity activities. The bracelets are typically made from 316L stainless steel and are often chunkier, designed to match the robust cases of dive watches. The focus is on function and resilience.

2. Design and Clasp Mechanism

A standout feature of this line is the Butterfly Buckle (also called a hidden or push-button deployment clasp). This clasp folds neatly underneath the strap, providing a seamless look that is far dressier than a traditional pin buckle. It also helps preserve the life of a leather strap by minimizing the bending and creasing when putting the watch on and taking it off. Other options use a simple Pin Buckle for a classic, slim profile.

The rubber straps utilize a heavy-duty Pin Buckle. This mechanism is simple, secure, and reliable for use underwater or during sports. Steel bracelets for dive watches will often feature a Folding Clasp with Safety and may include micro-adjustments or a diver's extension (though this needs to be confirmed on specific models) to allow the watch to fit over a wetsuit. The clasp design emphasizes security over discretion.

3. Compatibility and Target Audience

Product	Primary Compatibility Focus	Target Audience
Seagull Straps	Seagull watch models (e.g., 1963 Chronograph, Ocean Star, dress watches)	Those seeking an "Original" or OEM-quality replacement, or anyone who prefers a polished, classic look for their timepiece.
STEELDIVE Straps	STEELDIVE dive models (e.g., SD1953, SD1970, Willard homage), or any robust 20mm/22mm dive watch	Those who use their watch for active, outdoor, or wet environments; fans of the rugged "tool watch" aesthetic.
