Sea-Gull Boundary Series Mechanical Watch DIY Tool Kit 44mm
The Sea-Gull Boundary Series Mechanical Watch DIY Tool Kit lets you assemble a complete automatic wristwatch yourself, arriving in a DIY toolbox with every component ready to build. At its heart is the 2551K2 automatic movement with 24 jewels and a frequency of 21,600, wound by the motion of your wrist.
The 44mm round case and matching strap are both crafted from 316L stainless steel, protected by a synthetic sapphire crystal and secured with a pin buckle. A skeleton dial and luminous elements keep the mechanics in view and readable in low light, while 5 bar water resistance handles everyday splashes.
