While all cutting edge Rolex watches are fitted with crystals make from exceptionally scratch-safe engineered sapphire, more established Rolex watches were produced with crystals produced using a plastic-like material known as acrylic. The main Rolex watch to at any point be fitted with a sapphire crystal was the reference 5100, Rolex’s first-historically speaking quartz watch that was created as a restricted arrangement and fueled by the Beta-21 development. The reference 5100 appeared to the general population in 1970; be that as it may, acrylic crystals kept on being fitted to specific lines of Rolex watches into the mid 1990s.
Acrylic Crystals like this have been utilized by Rolex in the past
Acrylic crystals are essentially less scratch safe than their later-time, sapphire partners, and will definitely grow little checks and scratches on their surfaces, regardless of whether they don’t get any unpleasant treatment. Sapphire has a hardness of 9 out of 10 on the Mohs Hardness Scale, while acrylic plastics normally have a rating of around 3 or 4. Most commonly experienced metals and minerals have a hardness rating that ranges anyplace somewhere in the range of 5 and 8, which implies that when most of hard items come into contact with an acrylic crystal, they are probably going to leave a type of imprint or scratch.
This acrylic crystal has seen better days
While acrylic crystals do obtain flaws rather effectively, light scratches and scrapes can frequently be cured at whatever point they figure out how to happen. Any harm supported by a sapphire crystal is probably going to be lasting, while more minor imprints on acrylic crystals can be effectively eliminated at home inside a couple of moments, by essentially utilizing quite a few commonly accessible cleaning compounds, and a delicate cloth.
Although acrylic crystals are fundamentally less scratch safe than their later-time, sapphire partners, they are by and large better at enduring huge effects. Hardness evaluations identify with scratch opposition, instead of in general solidness. Sapphire crystals are “hard” and hard to scratch; be that as it may, they are inclined to chipping and breaking should a critical effect take place.

Whenever a sapphire watch crystal figures out how to break and break, the little, unbelievably hard crystal shards make perpetual imprints on the outside of the dial, and at last get into the internal functions of the development, requiring the watch to be expertly cleaned and adjusted. Acrylic crystals are innately more adaptable, and better at accommodating hard effects; be that as it may, when they do figure out how to break, they regularly break however hold together, as opposed to breaking and falling into the watch.

The smooth, hard surface of a sapphire crystal gives a watch a more current and refined look and believe, and its boss hardness guarantees that the essence of the watch will look clear and perfect for quite a long time to come. On the opposite side of things, numerous gatherers appreciate acrylic crystals for the warm, vintage appearance that they bring to a watch. Moreover, at whatever point a substitution crystal is required, acrylic crystals are altogether more affordable to supplant than their sapphire reciprocals. Neither acrylic nor sapphire can be viewed as an overall, “better” material for watch crystals, but instead each has its own, exceptional rundown of points of interest and drawbacks.
