Review: A different watch in the relatively low-priced Casio variants - Pictures: (1) Front (2) Diagnostic Mode showing all LCD elements (3) Module Number 3464 (4) Front Buttons (5) Right-side Buttons (6) Left-side Buttons and Full Front (7) Back (8) Back with Lugs and Strap (9) Clasp (10) Comparison with CA53 and F91 (11) Size comparison with F91 on hand Its the standard Casio watch, with 2 different features not seen before: Step counter and the 13-segment main digits instead of the standard 7-segment. More on these in this review below. Okay, so the price of this watch does __not__ beat the Amazfit Bip S watch that included step-counter along with other sports mode, and the awesome always-on display with so low battery consumption that I actually got 40+ days of battery life. But I liked the simplicity of this step-counting watch. You simply set your goal in the standard setup mode (long press top left button), though it can only be in multiples of 1000, and this watch starts counting. No need of any smartphone app, not nuisance of charging every day, or 7 days, or even 40 days. I expect the battery to last 2 years minimum (Casio claims this, and going by experience, their claims are usually conservative, it lasts way more than their claims). As far as the accuracy goes, I have tested the accuracy a few times by actually counting my steps and watching the watch, it seemed to match fairly accurately, though I am a little doubtful that overall during the day, it is probably showing more than what I am actually walking. Overall, it seems to be working well, considering it may not have ML models running inside to detect walking. As can be seen from images, it has 3 rows of display, top being dot-matrix, main being 13-segment digits, and bottom the standard 7-segment. I think the 13-segment doesn't make that much of a striking smooth difference, but I like it. :smiles: It has the standard modes: Home Time => Stop Watch (200 Laps Memory) => Timer (Max 59m59s only, a shame) => Dual Time (no World Time) => Alarm (Hourly Chime, 1 Snooze, 4 Alarms) Setting the minutes of Dual Time turned out to be unique: You can change it only in 15 minute intervals, i.e. 0, 15, 30, 45 minutes, instead of 1 minute in other low-end watches. It makes great sense: India is the only country with 30 minute difference (5h30m) and Nepal with 45 minutes (5h45m), so there is no need of each minute interval. There is no country with only 15m difference from the full hours, so availability of this option was unnecessary. But its easy to guess why they still provided it: either the programming was easier, or just to make it symmetric, or both. It is possible to mute the key-press beeps in the setup mode, which is not possible in very low-end Casio watches. The backlight is yellow LED that glows from left, which gives an uneven glow and not as elegant as the green backlights from a few years ago. But screen is visible in pitch dark. Final secret tip on getting into the Diagnostic Mode: Press Top-Left, Bottom-Left and Start-Stop Buttons all at the same time to see the first diagnostic screen, then just press Start-Stop Button to cycle through all other diagnostic information (incl. internal sensors). PS: The module number in the diagnostic screen was 3464 for me, however the back side had 3466 stamped (the number in the rectangle box on the steel back is the Module Number inside the watch). No, this is not fake, I have noticed such differences in a bunch of other Casio watches and have researched that they are still genuine (fake watches won't have diagnostic mode at all, and forget being so detailed about the LCD segments, dot-matrix and existence of internal sensors). ## Features - Dial Color : Grey Strap Color : Black - Step Counter::Stop Watch::Date Display::Alarm - Dual Time::Countdown Timer::Hourly Time Signal - 100-Water Resistance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KN8FLN2 | | Age Range Description | Adult | | Band Colour | Black | | Band Material | Rubber | | Band Style1 - Band Style5 | Modern | | Band Width | 5 Millimetres | | Best Sellers Rank | #12,031 in Watches ( See Top 100 in Watches ) #5,948 in Men's Wrist Watches | | Brand | Casio | | Case Diameter | 49.9 Millimetres | | Case Material1 - Case Material2 | Resin | | Case Shape | Round | | Case Thickness | 14.6 Millimetres | | Character | fashion | | Clasp Type | Double Locking Foldover Clasp | | Closure Type | Buckle | | Crystal Material | Resin | | Customer Reviews | 4.2 out of 5 stars 78 Reviews | | Dial Colour | Gray | | Display Type | Digital | | Embellishment Feature | Crystal | | Face Style | Guilloche | | Importer Contact Information | Imported By - Casio India Co Pvt Ltd, A-41, 1st Floor, MCIE, Mathura Road, New Delhi-110044 | | Item Type Name | Casual Watch | | Item Weight | 47 Grams | | Manufacturer | Casio India Co Pvt Ltd, A-41, 1st Floor, MCIE, Mathura Road, New Delhi-110044, Imported By - Casio India Co Pvt Ltd, A-41, 1st Floor, MCIE, Mathura Road, New Delhi-110044 | | Manufacturer Contact Information | Casio India Co Pvt Ltd, A-41, 1st Floor, MCIE, Mathura Road, New Delhi-110044 | | Model Name | WS-2100H-1A2VDF | | Model Number | WS-2100H-1A2VDF | | Movement Type | Quartz | | Part Number | D244 | | Power Source Type | Battery Powered | | Special Feature(s)1 - Special Feature(s)3 | Countdown Timer, Dual Time, Step Tracker, Stop Watch | | Sport1 - Sport3 | Walking | | Strap Type | Two Piece Strap | | Theme | Sports | | Unit Count | 1 Count | | Warranty Type | Extended | | Water Resistance Depth | 100 Metres | | Water Resistance Level | Waterproof | ## Images ![Youth Digital Grey Dial Unisex WS-2100H-1A2VDF (D244) - Image 1](https://m.media-amazon.com/images/I/61fvxMFbIkL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by P***H on 2 June 2025* Fantastic Watch, this was what I was looking for.
