This Seiko Prospex Speedtimer is a remarkable re - interpretation of Seiko's first space - worn automatic chronograph. It's inspired by the original Seiko Speedtimer 6139 livery and named 'Pogue' after Colonel William R. Pogue, who wore it during a crucial NASA Skylab mission. The case shape and visual identity stay true to the original, but modern touches like the hairline and smooth - polished bracelet and curved sapphire glass give it a contemporary look. Powered by Seiko's Caliber V192, it has a 24 - hour indicator, a time - of - day seconds hand, a 60 - minute chronograph in the six - o'clock sub - dial, and a power reserve function. Fully charged, it can run autonomously for about six months. With a 41.4 mm case diameter, made of stainless steel for both case and band, it features a solar movement, a curved sapphire crystal with an anti - reflective inner coating, Lumibrite on hands and indexes, a three - fold clasp with push - button release, and 10 - bar water resistance. Style#: SSC947.



Using this Seiko Prospex watch is easy. The 24 - hour indicator helps you keep track of time across different time zones. The chronograph at the six - o'clock sub - dial is great for timing events. Just press the buttons on the side to start, stop, or reset it. The time - of - day seconds hand gives you the current time accurately. As it's solar - powered, make sure to expose it to light regularly to keep it charged. When fully charged, it can run for about six months. For maintenance, keep it clean with a soft, dry cloth. Avoid exposing it to extreme temperatures or strong magnetic fields. If you want to clean it further, use a mild soap and water solution, but make sure to dry it thoroughly. The watch is water - resistant up to 10 bar, which means it can handle splashes and brief immersion in water, but don't wear it for deep - sea diving. The three - fold clasp with push - button release makes it easy to put on and take off, just press the button gently to open it.
