In-Depth Comparison

1. Horological Intent and Mechanical Philosophy

The fundamental difference lies in the purpose of the mechanism:

• Seagull Tourbillon Pendant (The Art Piece): This product is a tribute to haute horlogerie—high-end watchmaking. Seagull is renowned for making accessible mechanical complications, including tourbillons. The pendant features an eccentric tourbillon design in miniature as a sophisticated piece of jewelry. Crucially, the mechanism is not a functional timekeeper; it is a captivating visual display or 'moving concept' where the cage requires manual shaking or physical movement to create the intended swinging visual spectacle. Its value is in demonstrating craftsmanship and artistry in a portable form.
• Proxima Diver Watch (The Tool): The Proxima is an uncompromised functional timepiece built for utility, specifically diving. It focuses on reliability, accuracy, and durability. The choice of a high-beat, workhorse automatic movement (PT5000 or the Swiss-made SW200) prioritizes consistent performance and shock resistance over exotic complications. Its purpose is to tell time reliably under extreme conditions (200M water resistance).

2. Movement and Performance

Aspect	Seagull Tourbillon Pendant	Proxima Diver Watch
Complexity	Extremely high (Visually replicates a Tourbillon complication)	Standard/Moderate (Proven automatic caliber)
Utility	Zero timekeeping function (Aesthetic only)	High (Accurate timekeeping, hacking, manual winding)
Movement Option	Non-functional display module	PT5000 (Chinese-made, high-grade 28,800 VPH) or SW200 (Swiss-made Sellita, 28,800 VPH)
Accuracy	N/A	Excellent potential accuracy due to high-beat rate, especially with the SW200 option.

3. Design, Form Factor, and Durability

• Form Factor: The Seagull is a miniature, 19mm circular pendant designed to be worn on a neck chain (often titanium). It is a delicate statement piece. The Proxima is a full-sized 39.5mm wristwatch, a substantial piece of 316L stainless steel that is ruggedly built.
• Durability: The Proxima is built as a tool: 200M water resistance via a screw-down crown, a scratch-resistant sapphire crystal, and a fully lumed ceramic bezel for functional measurement underwater. The Seagull pendant is a decorative item. While the chain is described as titanium, the intricate display mechanism would not be expected to withstand moisture or significant shock.
• Luminosity: The Proxima utilizes Swiss Super Luminova BGW9, providing excellent, long-lasting illumination in low light conditions—essential for a dive watch. The Seagull pendant does not feature any time-telling or luminous features.

4. Price and Value

The price point is relatively similar, yet the value proposition is vastly different:

• The Seagull Pendant offers value in exotic complexity and artistry for its price range, allowing an enthusiast to own a wearable representation of a costly tourbillon movement.
• The Proxima Watch offers value in functional specifications and mechanical quality. For a mid-range price, you receive a watch with premium components like sapphire glass, ceramic bezel, 200M water resistance, and a highly regarded high-beat movement (PT5000 or SW200).
