Description
An elegant, rectangular dress watch that punches far above its weight class in terms of specs. The Casio Beside BEM-100D combines the functionality of a daily-wear quartz watch with the refined aesthetics of high-end Swiss dress pieces. Its standout feature is the inclusion of a sapphire crystal at a price point where mineral glass is standard. The 'tuxedo' dial and date at 6 o'clock create a symmetrical, sophisticated look suitable for formal occasions or professional office wear.
Key Features
Sapphire crystal branding on the dial, date window at the 6 o'clock position for symmetry, and the 'Beside' sub-branding which is rarer in Western markets compared to Asia and Europe.
Dial Description
Silver sunburst center with a vertical striped 'tuxedo' texture on the outer perimeter. Features applied polished baton indices and a framed date window at 6 o'clock. The hands are alpha/sword style with narrow luminous strips.
Case Material
Stainless steel. The case features a brushed finish on the flat surfaces and polished finishing on the curved vertical flanks and crown.
Crystal Type
Flat Sapphire Crystal. Features high scratch resistance; noticeably flat with a subtle chamfered edge at the bezel line.
Bezel Details

50 Meters (5 ATM). Suitable for light swimming or showering, but not recommended for diving or high-impact water sports. The push-pull crown is a limiting factor for deeper submersion.
Origin & Provenance
Japanese Movement, cased/assembled in China or Thailand. Uses a Casio in-house quartz module.
Age Estimate
Circa 2005-2015. This specific line was popular in the mid-to-late 2000s as an affordable alternative to luxury rectangular watches.
Cultural Significance
Represents the 'Value Proposition' movement in watch collecting, proving that horological appreciation doesn't require five-figure investments. It influenced the current trend of 'affordable integrated' watches.
Condition Notes
Good condition. The case and bracelet show significant surface scratching (desk diving marks) consistent with regular use. The sapphire crystal appears clear and scratch-free, demonstrating its durability.
Value Estimate
$50 - $120 USD. Value depends on bracelet tightness and presence of original packaging. It is a discontinued model and has a niche following among 'Value' collectors.
Care & Maintenance
Battery replacement every 2-3 years. Since it is a snap-back case, the gasket should be checked during battery changes to maintain its 50m rating. Bracelet can be cleaned with a soft brush and mild soap.
