Casio F-B100W Restock Expected in September, But Getting One May Still Be Difficult
Casio’s new F-B100W is proving to be one of the hardest digital watches to buy in Japan right now. After selling out quickly following its launch, Japanese retailers are now beginning to list fresh delivery dates for the popular Bluetooth-enabled model. However, anyone hoping to grab one immediately may need to stay patient.
Several watch shops in Japan are reportedly pointing to early September as the next restock window for the Casio F-B100W. That sounds promising at first, but there is an important catch: much of the incoming stock is expected to be used to fill existing back-orders. Because demand has been building since launch, shoppers without a reservation may not see freely available stock until later in September.
The shortage appears to be the result of strong early demand combined with unfortunate timing. Preorders for the F-B100W opened on August 1 and were reportedly cleared within days. The watch officially went on sale on August 7, shortly before Japan’s Obon holiday period, when many businesses pause or slow operations. That timing meant distribution stalled just as buyers were trying to secure the new model.
Once the holiday period ended, a small number of units briefly appeared again through Casio’s official online store in Japan, but they did not last. The watch is currently difficult to find through regular retail channels, and the next wave of shipments may not be enough to satisfy demand right away.
Part of the excitement comes from the F-B100W’s familiar design. Casio has taken inspiration from the legendary F-91W silhouette, a compact and affordable digital watch known around the world, and added modern features. The result is a retro-style digital watch with Bluetooth connectivity and activity-tracking functions, giving buyers a blend of old-school Casio charm and everyday smart features.
The F-B100W connects to the Casio Watches app and supports a monthly life log. It can track steps and estimated calories burned, allowing users to compare daily activity against personal goals. It is not designed to compete with full smartwatch models, but that may be exactly why it is attracting so much attention. For many buyers, it offers the simplicity of a classic Casio watch with just enough connected functionality to feel useful.
The F-B100W lineup includes different display styles, including a black model with a negative display. This version appears to be especially desirable among collectors and casual buyers alike. Negative displays often give digital watches a stealthier, more modern appearance, although some users prefer positive displays for easier readability.
In Japan, the Casio F-B100W launched at ¥8,800. The model has also reached the UK market, where it was listed at £55. The black version has already sold out there as well, suggesting that demand is not limited to Japan.
What makes the F-B100W interesting is that it sits in a sweet spot for Casio fans. It is more advanced than a basic budget digital watch, but it remains far simpler and more affordable than many fitness trackers or smartwatches. It keeps the lightweight case and practical personality that made Casio’s classic digital watches so popular, while adding features that suit modern daily routines.
For now, buyers in Japan should expect the next deliveries to begin around early September, but availability may remain tight. Because retailers are likely to prioritize existing back-orders, the best chance for general shoppers may come toward the end of September if supply improves.
The Casio F-B100W has quickly become one of the most talked-about digital watches of the season. Its combination of nostalgic design, Bluetooth support, motion sensing, activity tracking, and accessible pricing has created a level of demand that Casio may need time to catch up with. If you are hoping to buy one, keeping an eye on retailer restocks throughout September will likely be essential.
