Important facts

The Seiko Astron SSH021J1 has a sapphire crystal which provides a durable and clear viewing surface for the dial. This type of crystal is highly resistant to scratches and does not discolor over time. Sapphire is also resistant to most chemicals and less likely to shatter compared to other materials, making it a safer choice for the watch wearer. Thefore sapphire is a good choice for high-end wristwatches. It is of course an expensive option, compared to other materials, like plexiglass.

The case of this watch is made out of stainless steel which is a strong and durable material, therefore being resistant to scratches, dents, and general wear and tear. Steel is also highly resistant to corrosion and rust, but is also a hypoallergenic material, which means that it is less likely to cause skin irritation or allergic reactions.
