The spring bar tool is the most important device for watch strap changes. There are a wide range of spring bar tools available in the market today. From very basic manufacturing that 'does the job' to highly precise ones that requires high costs to procure.This tool is great to handle during strap change due to its engineering details and are made in Japan with great quality. One end has an 'I' tip or straight pin pusher at 0.8mm and protrusion at 5.6mm. The other end has a 'Y' tip or a fork profile that has a curved profile that is able to hold a compressed spring bar in position without letting it eject or 'fly off' in the process of removal. Both tips are made of high-carbon hardened, tempered steel alloy and their distinct matte-black appearance is the result of a deliberate chemical treatment known as black oxide. Despite being some of the hardest tip in the market, it is still subjected to deformation if excessive force is applied to it.The body of the tool is lightweight made of aluminum. The pleasure of using this tool is the cross hatch, knurled grip positioned strategically at the right distance from the tip for most effective removal of the spring bar.Best suited for leather, rubber and brafic strap changes that does not require both side of the spring bar to be compressed simultaneously.Total Tool Length: 100 mm to 104 mm (approx. 4 inches)Tool Weight (Bare): 10 grams (0.35 oz)Handle Body Diameter: 6 mmY-Tip Geometry (Fork)Standard watchmaker profile width (optimized for regular straps)I-Tip Geometry (Pin)Diameter: 0.8 mmMeasurement Scale Engraved: 30 mm / 1.2-inch reference ruler on the grip
