The latest chatter from Casioblog hints at Casio rolling out fresh watches in its Beside series as part of the BMS-500 collection, a throwback style chronograph that’s eyed for a June 2026 debut. This model line sits after the BMS-100 and BMS-300, with whispers that the module is a step up from its older kin.
Four variants and material choices
There are four versions arriving together: two with a stainless-steel bracelet labeled BMS-500D-1A and BMS-500D-7A, and two with a leather strap labeled BMS-500L-1A and BMS-500L-7A. The suffix decodes the dial color — 1A equals black, 7A equals white. The bracelet and strap versions diverge primarily in the sub-dial styling: leather models showcase sub-dials in a contrasting hue against the main dial.
Dial details and layout
The dial sports Roman numeral hour markers, and at the 4 o’clock mark the design sticks with the traditional “IIII” instead of “IV.” Chronograph sub-dials sit at 9 o’clock to mark a 60-minute counter, plus a secondary indicator that reveals 24-hour time. The central seconds hand tracks elapsed time during stopwatch use, and a date window is included for daily practicality.
The case measures 48.0 × 43.6 × 10.8 mm in stainless steel, with reinforced lugs for both bracelet and strap configurations. Water resistance is rated to 50 meters, and the movement delivers around ±20 seconds of accuracy per month, while the battery life is pegged at about five years.
noteworthy hardware and pricing
One standout spec for this price tier is the inclusion of sapphire crystal across all four BMS-500 variants, a feature not always common in this segment. This is likely to appeal to buyers seeking durability and clarity. Price expectations place leather-strap models starting near $70, with bracelet versions climbing to roughly $120.
Global availability details remain unconfirmed beyond a June 2026 launch window in Japan, leaving the rest of the world to wait for more updates.
