The properties of tungsten make this the perfect metal for watch making. A rating of between 8 and 9 on the Mohs scale of hardness, sitting just below Diamonds means it is extremely strong and scratch resistant. Tungsten is also able to take an extremely high polish giving it an attractive mirror like finish. A Yellow gold fused stainless steel case and link hold the entire creation together, whilst a precision quartz movement works silently away under a designer grey dial emblazoned with 4 of our flawless created Diamonds. Magnificent presentation case.
