Prospex Speedtimer Mechanical Watch. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by a heritage of iconic design, Prospex continues to keep going forward with excellence in precision timekeeping, crafted for the modern world. Based on Seiko’s Speedtimer models of the past, this powerful creation offers superior timekeeping combined with sporty elegance and wearing comfort. Framed by a countdown timer dial ring that can be utilized to measure the remaining time of a particular event, the hairline-finish charcoal dial displays the word “Speedtimer,” honoring Seiko’s legacy of sports timing. The sporty dial is accented by an orange-tipped second hand and offers a date calendar and LumiBrite hands and markers for superior visibility in low light conditions. With an upgraded power reserve of approximately 72 hours, 3 full days, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour with manual winding capability. Crafted of stainless steel with super-hard coating, this rugged yet refined watch is 200 meter water resistant while boasting the slimmest case of any Seiko 6R model, flowing seamlessly from the case to the multi-row bracelet. Topped with a curved sapphire crystal with anti-reflective coating on the inner surface, it includes a screwdown crown and caseback, and a tri-fold push button release clasp.

Ralph has many great watch brands starting from your usual Seiko’s, Citizen’s, Bulova, etc. to more upscale such as Longines, Hamilton, Oris, etc. the variety is good and overall I like their prices are fair and reasonable, especially if they have a sale. I’d buy a watch from them again in the future.
