What the 45 mm case means for fit
At 45.0 mm in diameter and 13.4 mm thick, the listed dimensions are important to consider before buying. The watch has a 22 mm lug distance and comes on a silicone band, so anyone considering a replacement strap should choose one specified for 22 mm lug width and confirm its fit with the seller. The official specification does not establish how the watch will wear on a particular wrist.
Movement and everyday functions
The 4R36 is an automatic movement that can also be wound manually. Seiko lists approximately 41 hours of power reserve, 24 jewels, stop-seconds, and a day/date display for this model. The listed reserve is approximate; no model-specific accuracy measurement is established here.

Seiko USA’s October 8, 2021 announcement gave suggested retail prices of $750 and $785 for three U.S. sea-turtle special editions announced within the same conservation-oriented family. Those figures are not a current U.S. price for the SRPC91K1, so they should not be used as one.
Seiko presents Save the Ocean as a conservation-linked initiative, with projects relating to marine debris, polar research, underwater archaeology, and sea-turtle conservation. Its stated Prospex mission is “to help protect the world’s oceans now and for future generations, and to secure this legacy for divers everywhere.” Seiko USA’s 2021 announcement tied a portion of proceeds to Oceanic Society work for the U.S. models it discussed; that statement should not be assumed to apply to every SRPC91K1 sale.
