Acrylic Crystal

Highly impact-resistant

Acrylic lens are a specialised form of plastic akin to Plexiglass and were commonly used in early to mid-20th century watches. It is a softer material that can be more prone to scratches but conversely is very shatter-resistant. Given its softness any scratches though can be buffed out. Acrylic lens are synonymous with vintage-inspired timepieces and thus can be found on our Marlin and Q Timex collections.
