Aeromotive Pump Speed ControllerFor any pump, on any type of vehicle, the Aeromotive Fuel Pump Speed Controller (FPSC) minimizes fuel heating and vapor lock problems by matching the duty cycle of the fuel pump to engine RPM. At low demand, the FPSC slows the fuel pump down, reducing the chance of suction side cavitation and vapor lock. When demand increases, the FPSC returns the fuel pump to 100% duty cycle for maximum flow. It? s like an automatic transmission for your fuel pump.

I love this watch. Dial and movement are fascinating. It’s quite a show when the chrono is engaged, the timekeeping central seconds hand conyinues sweeping around, and the chrono’s central seconds hand is also sweeping. So you have two central seconds hands chasing each other around the dial when the chrono is engaged. On the retrograde subdial displays, time for a second time zone is displayed when chrono is not engaged. Elegant logo counterweight on one hand. Lots of content, complication and engagement for very little money. Highest recommendation for those interested in a watch that has a lot to offer.

Very nice watch for the money!

Little heavier than I thought. Weighs about 7 oz. the band itself weighs 4 oz. I replaced it with a much lighter leather band. Much more comfortable.

Fly back / duel time zone / under 200 bucks!!!!!

Color: Stainless Steel, Color: Stainless Steel

Incredible people don’t realize Timex is American history. It’s heavy and it’s a flyback chronograph with a dual time., that’s an expensive complication on any other watch. This would be thousands , it’s almost like a fidget toy lol , you have six hands that are working you can dual time on the chronograph as it flies back and have dual time zones for the money. It’s a no-brainer.
