GFB Whistling Trumpet (only for Stealth FX and WRX Hybrid)The 5701 can be used in place of the standard trumpet on GFB valves (Part numbers T9003 & T9503), and will make a whistling sound. However, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50 50 venting.

Utilitarian watch
This inexpensive watch fulfills its purpose adequately. It is easy to read, water resistant and fairly attractive. However the band length is just sufficient and the band itself is very stiff, even for a new watch.

Luxurious looking watch for great price
The watch is simple yet, it looks expensive. The material of the watchband is high quality and holds its shape well.
