Unveiling the Finest Details: The Materials that Go Into Rotary Watches

When it comes to selecting a timepiece, Rotary Watches has long been synonymous with timeless elegance and superior craftsmanship. As you explore the world of Rotary Watches, you may come across terms like mineral glass, sapphire glass, stainless steel, and PVD.

The first point of contact for any watch enthusiast is the watch's face, which is often protected by a transparent material known as the watch crystal. Two popular options are mineral glass and sapphire glass. So what is the difference between mineral and sapphire glass?

Mineral Glass:

    Mineral glass is a durable and cost-effective material commonly used in watches. It is made by hardening glass through a tempering process, enhancing its resistance to scratches and impacts. While mineral glass offers good protection for everyday wear, it is not as scratch-resistant as sapphire glass. However, its affordability makes it a practical choice for those seeking a reliable timepiece without breaking the bank.

    Sapphire Glass:

      Sapphire glass is known for its exceptional hardness, making it highly resistant to scratches and impacts. Derived from synthetic sapphire crystal, it ranks just below diamonds on the Mohs hardness scale, ensuring long-lasting clarity and resilience. While it is more expensive than mineral glass, sapphire glass provides an unmatched level of durability and is often found in luxury and high-end watches. Its scratch-resistant properties make it an excellent choice for those who desire a timepiece that maintains its pristine appearance for years to come.

      Apart from the watch crystal, the watch case itself plays a significant role in defining the overall aesthetic and durability of a timepiece. Rotary Watches offers both stainless steel and PVD gold stainless steel options, each with its own characteristics.

      Stainless Steel:

        Stainless steel is a popular choice for watch cases due to its strength, corrosion resistance, and timeless appeal. It is an alloy composed of iron, carbon, and chromium, which gives it its resistance to rust and tarnish. Stainless steel watches exude a classic and versatile look suitable for various occasions, from casual to formal settings. They offer durability, longevity, and a refined aesthetic that withstands the test of time.


          PVD (Physical Vapour Deposition) is a process used to create a thin, durable coating of gold colour on stainless steel watches. PVD gold stainless steel offers the allure and elegance of gold without the hefty price tag of solid gold watches. This coating is more resistant to fading and wear than traditional gold-plated watches, providing a longer-lasting golden hue. The combination of stainless steel's durability and PVD gold's luxurious appearance makes it an appealing choice for individuals seeking a touch of opulence. We also offer black PVD coatings too, which allow for a matte black finish. See our Pilot Black Edition for an example of a black PVD watch.

          Whether you opt for mineral glass or sapphire glass, stainless steel or PVD gold stainless steel, Rotary Watches offers a range of timepieces to suit your personal taste and lifestyle. The choice ultimately comes down to your preference for durability, scratch resistance, and aesthetic appeal. Regardless of the materials chosen, Rotary ensures a commitment to quality and craftsmanship that has made them a trusted name in the world of horology.
