The Venezianico Nereide GMT is a versatile Italian-designed sports watch that combines the rugged construction of the Nereide dive-watch collection with the practicality of a mechanical GMT complication. This pre-owned example is presented in mint condition and was originally purchased in February 2024.
Reference 3521504C features a striking sunray-finished dial, distinctive two-tone 24-hour GMT bezel, and Venezianico’s stainless steel Canova bracelet. Its combination of compact proportions, sapphire crystal, 200-meter water resistance, and automatic GMT movement makes it equally suited to travel, everyday wear, and more adventurous use.
The Nereide GMT is housed in a compact 39mm 316L stainless steel case measuring 45.5mm lug-to-lug and 13.4mm thick. These dimensions provide a substantial sports-watch presence while remaining highly wearable on a wide variety of wrist sizes.
One of the most distinctive features is the BK7 optical crystal bezel insert. Rather than using a conventional aluminum or ceramic insert, Venezianico selected BK7 optical glass for its clarity, low dispersion, and polished appearance. The lower portion incorporates a mirror-like finish that gives the GMT bezel additional depth and visual character.
Powering the watch is the proven Seiko NH34A automatic GMT movement. The 24-jewel caliber operates at 21,600 vibrations per hour and provides approximately 41 hours of power reserve, along with manual winding, hacking seconds, date functionality, and a dedicated independently adjustable 24-hour GMT hand.

The Venezianico Nereide GMT offers an appealing combination of Italian design, dive-watch capability, and practical GMT functionality. Its compact 39mm case and 45.5mm lug-to-lug dimensions make it particularly wearable, while the 200-meter water resistance and screw-down crown provide the durability expected from the Nereide platform.
The BK7 optical crystal GMT bezel is one of the details that separates this watch from more conventional GMT designs. Its polished surface and mirrored lower section interact with changing light to create additional depth around the sunray-finished dial.
Inside, the Seiko NH34A provides a reliable and easily serviceable automatic GMT platform with 24 jewels, hacking, manual winding, date functionality, and approximately 41 hours of power reserve. The engraved world-time caseback and Canova stainless steel bracelet complete a design that is equally at home during international travel or everyday wear.
