The Seiko Prospex LX SNR058 is a U.S. Special Edition GMT with a titanium case and bracelet, a nebula-inspired brown-to-black dial, and Seiko’s 5R66 Spring Drive movement. Seiko currently lists it for $6,600; that is the price shown on its product page, not a verified transaction price.
What is the Seiko Prospex SNR058?
The SNR058 is part of Seiko’s Prospex LX line and is identified on Seiko’s official product page as a “PROSPEX LX U.S. SPECIAL EDITION.” It combines a second-time-zone GMT function with a titanium case and bracelet. Seiko’s product description says its brown-to-black dial draws inspiration from the North America Nebula, approximately 2,000 light years from Earth, according to Seiko.
The dial has a glossy dual-tone sapphire GMT bezel with rose-gold accents and a rose-gold-tone GMT hand. Those are Seiko’s descriptions of the design and materials; they are not independent material test results.
How much does the Seiko SNR058 cost?
Seiko currently lists the SNR058 at $6,600 on its U.S. product page, which also links to a store locator. The page does not establish live inventory or confirm a sale at that price. Notebookcheck’s December 10, 2025 launch report said pricing and retail availability details had not been supplied at the time; its page was updated October 5, 2026. The later official listing provides the current stated price, but neither source confirms current store stock.

- STAINLESS STEEL CASE built to endure with style, making this watch your perfect daily companion
- AUTOMATIC MOVEMENT for seamless precision in every tick of this watch

What movement is in the SNR058?
The watch uses Seiko’s 5R66 Spring Drive GMT caliber. It is automatically wound and can also be wound manually. Its mainspring supplies the power, while a quartz oscillator is part of the regulation system; it is not a battery-powered watch. The movement’s second hand uses Spring Drive’s glide motion rather than conventional ticking. Seiko’s 5R65/5R66 instruction manual explains the system and the 5R66’s time-difference adjustment for travel between time zones.
5R66 functions and stated performance
- Second-time-zone GMT function with time-difference adjustment
- Date calendar and power-reserve indicator
- 30 jewels
- Approximately 72 hours of power reserve
- Seiko-stated accuracy of ±1 second per day or ±15 seconds per month
Case size, materials and water resistance
Seiko lists a 44.8 mm case diameter, 14.7 mm thickness and 50.9 mm length. The case and bracelet are titanium with super-hard coating; the listed lug width is 22 mm. The crystal is sapphire with super-clear coating. The watch is rated to 10 bar (100 m / 330 ft) and has a screw-down crown and caseback, according to Seiko’s specifications. Its bracelet uses a tri-fold push-button release clasp.

These dimensions make the SNR058 a substantial watch on paper, particularly in thickness and length. Those measurements are useful for assessing fit, but they cannot establish how it will wear on a particular wrist.
How does the SNR058 compare with the Seiko SNR033?
The SNR033 is a related Prospex LX 5R66 model, not another name for the SNR058. Seiko’s official U.S. listing gives the SNR033 a $6,000 price and shares several core specifications with the SNR058. Its styling and functions differ, so the two should not be treated as interchangeable.

The shared caliber, case diameter, thickness, titanium coating and water-resistance rating make the SNR033 a useful reference point. The SNR058’s official listing is $600 higher, and its longer case dimension and distinctive GMT styling are specifically stated on its product page.

Seiko identifies the model as a U.S. Special Edition. Notebookcheck described it as U.S.-exclusive in its launch coverage and reported that no fixed production number had been announced.
