KUOE Old Smith 90-007 Automatic 35mm Watch with Blued Hands #OS90007-ABL-IT-DBR-SA

The Old Smith 90-007 is a small seconds, automatic watch.

Equipped with CITIZEN MIYOTA's Japanese-made Cal. 82S5 movement, this model is inspired by antique watches of the 1930's and is designed with classic details and styling to create an vintage atmosphere.

The OLD SMITH 90-007 has thermally blued elegant leaf hands. Bluing is an old technique used to make steel more corrosion resistant but has fallen out of favor in recent years due to the low cost of stainless steel. In modern times, this technique is often emulated with paint, but KUOE has decided to use true blueing for this model. This model also has "curved hands", in which the tip of the minute hand curves along the glass, which was common in watches made several decades ago. This hand design is easily readable while at the same time maintaining a sense of luxury.

The diameter of the main body is a small 35mm case, which is typical of KUOE. Smaller than many modern watch designs, this 35mm case size is a good fit for most wrist sizes.

What is blued steel?
Blued steel is a metal that has been "blued." The bluing used for the ROYAL SMITH 90-010 hands are specifically "hot" blued. When the steel is heated, it oxidizes and changes color. The color changes in order from yellow, to brown, to dark brown, and finally blue. Steel treated in this process is called "blued steel" due to the distinctive blue color. Shortly after the blue color, the metal turns gray, so the timing is very important to achieve a beautiful the desired blue color, making it a very time-consuming and expensive process. Bluing is an old technique used to make steel more corrosion resistant but has fallen out of favor in recent years due to the low cost of stainless steel. In modern times, this technique is used only in high-end wristwatches, so KUOE has chosen to use it for this commemorative model.
