Is your Pro Diver
the real deal?
The Invicta Pro Diver is one of the most popular affordable watches in the world. Its Submariner-inspired design and budget-friendly price have made it hugely popular — and a frequent target for even cheaper counterfeits. Here's how to tell if yours is genuine.
How to authenticate a Pro Diver
Seiko NH35A Movement (Display Case Back)
The automatic Pro Diver features a Seiko NH35A movement visible through a display case back. Look for the "NH35A" marking on the movement, along with "24 JEWELS" and the Seiko logo. The rotor should spin freely and smoothly. Counterfeits often have unmarked movements or a solid case back where there should be a display window.
Unidirectional Bezel (120 Clicks)
The Pro Diver's bezel should rotate counterclockwise only with 120 precise, tactile clicks. Each click should feel distinct and the bezel should have zero back-play. The bezel insert markings should be evenly spaced and clearly legible. Counterfeits often have bidirectional bezels or sloppy click mechanisms with noticeable play.
Screw-Down Crown
The Pro Diver features a screw-down crown for water resistance. It should thread smoothly into the case tube with a secure, positive lock. The crown should feel solid with no wobble. Counterfeits often have a push-pull crown that simply pushes in rather than screwing down, compromising the water resistance.
"INVICTA" Logo on Dial & Crown
The "INVICTA" name should be clearly and crisply printed on the dial, typically below the 12 o'clock position. The crown should also feature the Invicta "I" logo or name. Both should use the correct font with clean, sharp edges. Counterfeits often have blurry dial printing or a blank, unmarked crown.
Case Back Model Number & Water Resistance
The case back should be engraved with the model number (e.g., 8926OB or 8928OB), "INVICTA" branding, water resistance rating (200M / 660FT), and material specification. All engravings should be deep, crisp, and consistent. The model number should match the watch design when cross-referenced with Invicta's catalog.
Bracelet Clasp with Invicta Branding
The fold-over clasp should feature the Invicta name or logo engraved or stamped on the surface. The clasp mechanism should lock securely with a positive click and open smoothly. The bracelet links should be solid with consistent finishing and no sharp edges. Counterfeits often have unbranded clasps or poor-quality stamping.
Pro Diver counterfeit warning signs
Non-Screw-Down Crown
The genuine Pro Diver has a screw-down crown for its 200m water resistance rating. If the crown simply pushes in and pulls out without threading, the watch is counterfeit. This is one of the easiest and most reliable checks, as it requires no tools or expertise.
Bidirectional Bezel
A genuine Pro Diver bezel rotates in one direction only (counterclockwise). If the bezel rotates freely in both directions, the watch is counterfeit. A proper dive bezel is unidirectional as a safety feature to prevent accidentally reducing remaining dive time.
Missing Display Case Back
The automatic Pro Diver models (8926OB, 8926 series) feature a transparent exhibition case back that reveals the Seiko NH35A movement. If an automatic model has a solid case back, or if the visible movement lacks Seiko markings, the watch is not genuine. Note: quartz Pro Divers have solid case backs by design.
Poor Lume Quality
Genuine Invicta Pro Divers have luminous material on the hour markers, hands, and bezel pip that glows clearly in the dark after light exposure. Counterfeits often have weak or absent luminous material, or the lume fades extremely quickly (within seconds rather than hours). The lume should glow evenly across all markers.

Frequently asked questions
What is the difference between the automatic and quartz Pro Diver?
The automatic Pro Diver (e.g., 8926OB) uses a Seiko NH35A self-winding movement with a display case back and sweeping second hand. The quartz version uses a battery-powered Japanese TMI movement with a solid case back and ticking second hand. The automatic version needs regular wearing or winding to stay running, while the quartz version runs continuously on a battery for about 2-3 years.
What are the specs of the Seiko NH35A movement?
The Seiko NH35A is a reliable Japanese automatic movement with 24 jewels, a 41-hour power reserve, and a beat rate of 21,600 vibrations per hour (6 beats per second). It features hacking (the second hand stops when the crown is pulled) and hand-winding capability. The movement is known for its durability and accuracy of approximately +/-20 seconds per day.
Is the Invicta Pro Diver really water resistant to 200 meters?
The genuine Invicta Pro Diver is rated for 200 meters (660 feet) of water resistance, which is sufficient for recreational swimming and snorkeling. This requires the screw-down crown to be fully tightened and the gaskets to be in good condition. The water resistance should be tested periodically, especially if the watch has been opened for battery changes or service.
