Full watchmaker tool kit
We are here to help
Building an automatic watch is a challenging task, but with our complete sets you will receive the prepared components for assembly, a full tool kit and detailed step by step instructions. All you need is a steady set of hands and a bit of patience, to complete this kit!
The Mayfair is a mix of elegant curves, subtle brushed surfaces and finely polished edges with a sunray brushed, colour infused dial. Now we took a cutter to this outstanding dial to reveal the beating heart of the Mayfair! With its oval cut-out this open heart design reveals not just the spinning balance wheel, but also the escapement lever and wheel completing the mechanism as well as the gear train connected all the way to your hands. After having spent the time and effort of building your watch, you can monitor its function with a glance at your wrist.
Measuring 40mm the Mayfair case is an elegant case, but retains key features of a toolwatch such as a scratch resistant sapphire crystal and a screw-down crown and case back to ensure water resistance. Within the case a 28.5mm fume dial features a sunray brushing to reflect the light with every movement of your wrist, completed by a set of elegant silver polished, lume filled hands. The Mayfair is powered by the NH-38A automatic watch movement with 41 hours power reserve, 24 jewel bearings and sweeping second hand.
Containing all parts, tools and instructions our kits are an ideal start into the world of horology. Learn more about the way a watch ticks, the origins of watchmaking and how to assemble your own automatic watch at home.
All our kits contain a detailed instruction booklet as well as access to our step-by-step video guides available on our homepage (click here for an example) to assist you throughout the assembly.
