Precision and beauty are on display in the Jazzmaster Skeleton. Hamilton's bold design signature is integrated into a cut-out dial that reveals the highly technical internal mechanics of this captivating and unique timepiece. Within the sleek 40mm stainless steel case, the H-10-S movement has the capacity to store double the power of comparable standard movements, offering an extended power reserve of up to 80 hours. The case is made from high-grade stainless steel which features a polished finish. The crown rests at the 3 o'clock position which once pulled out can be used to adjust the time. The sapphire crystal glass sits in line with the case which allows it to reside neatly underneath a shirt. The strap is made up of a black leather material which features detail in the stitching seen on each side. The lug width is 20mm which is complemented well by the case size. The most eye-catching part of this watch is definitely the dial. It features a skeleton design which allows you to see the intricate workings of the watch. The ruby, also known as the heart of the watch, rests at the 12 o'clock position. Perhaps to the untrained eye it may be missed but the skeleton window is designed in such a way that the Hamilton 'H' takes to the centre stage of this piece. Furthermore, the ever present Hamilton logo can be seen at the 3 o'clock position. Around the outside of the dial are silver indexes which sit in-between the case and hands, of which are powered by a quartz movement. Additionally, the hands are coated in a luminous material which allows for easy visibility at night. The H-10-S movement offers an extended power reserve of up to 80 hours. This watch has a water resistance of 50 metres, making it suitable for surface swimming.
