About this timepiece
Prospex Speedtimer 40th Anniversary Limited Edition. Designed for those who treat life as the ultimate adventure, Seiko Prospex keeps moving forward, meeting every challenge with technological excellence and winning design. This extraordinary Limited Edition, available only in a controlled-production run of 4,000, with the serial number engraved on each caseback, celebrates the 40th anniversary of the first analog quartz chronograph equipped with a 1/100-second stopwatch. Featuring the new solar chronograph 8A50 movement, this exceptional watch includes a highly legible, uniquely designed dial with a warm charcoal gray base and four inset black subdials, separating the time dial from the chronograph indicators, and LumiBrite hands and markers. The chronograph function measures up to 60 minutes of elapsed time in 1/100-second increments and provides a split time function, while the solar cell, powered by any light source, with no battery change required, offers a 6-month power reserve when fully charged. To allow easy utilization of the stopwatch feature, this precision watch features concave tops on the hammer-shaped pushers. With a curved anti-reflective sapphire crystal, this rugged stainless steel timepiece includes stylish black center links, a screwdown caseback and tri-fold push button release clasp. 10 bar, 100M Water Resistant

Care Instructions
Daily Care
• Wipe the case and bracelet with a soft microfiber cloth after wear to remove oils, dust, and fingerprints.
Cleaning
• Use a soft cloth lightly dampened with water and mild soap for occasional cleaning.
• Dry the watch thoroughly with a clean, soft cloth.
What to Avoid
• Avoid bleach, chlorine, harsh chemicals, abrasive cleaners, and household cleaning products.
• Do not use polishing compounds unless specifically recommended by the watch manufacturer.
Stainless Steel and Titanium
• Light surface marks may develop over time with normal wear.
• Titanium can show cosmetic marks differently than stainless steel because of its lighter weight and surface characteristics.
Water Resistance
• Always follow the water resistance rating listed by the manufacturer for your specific watch.
• Water resistance is not permanent and can decrease over time as seals and gaskets age.
• Make sure the crown is fully pushed in or screwed down before water exposure.
• Do not operate the crown, pushers, or other controls while the watch is underwater unless the manufacturer specifically states that it is safe to do so.
• Avoid hot tubs, saunas, and very hot showers, as heat and rapid temperature changes can affect the watch seals.
• Have the water resistance checked periodically, especially after battery replacement, case opening, or service.
Storage
• Store your watch in a clean, dry place when not in use.
• Keep it separated from other jewelry or watches to help prevent scratches.
