F-B100W-1A, 1B and 3A: choose by the full reference
The suffix after the F-B100W model name identifies a particular regional or colour variation. Do not choose only from the thumbnail image. Check the seller’s full reference number, dial and band colour, warranty information, and whether the watch is intended for your market.

|---|---|---|
| F-B100W-1A | Full reference, listed colour details, seller and delivery estimate | Open the listing and match the complete code |
| F-B100W-1B | Complete product title, returns policy and warranty information | Compare seller terms before ordering |
| F-B100W-3A | Official-looking model code in the description, not only a shortened title | Confirm the exact configuration with the seller listing |

Before checkout: 4-point buying checklist
- Match the full reference: do not buy based only on “B100W” in a search result.
- Confirm shipping: check whether the retailer delivers to your country and whether import charges may apply.
- Check seller protection: review seller rating, returns policy, and warranty terms.
- Compare the final price: include shipping and taxes, not only the product price.

F-B100W buying FAQ
How do I make sure I am buying the right F-B100W variant?
Compare the full model reference in the product title and description, then check the listed colour, seller, warranty, and returns policy. Product thumbnails and shortened titles are not enough on their own.
Can I buy the F-B100W internationally?
It depends on the individual seller and destination. Check the listing’s delivery availability, estimated arrival date, import charges, and return policy before placing an order.
Should I choose an F-B100W or a G-SHOCK?
Choose the F-B100W for a lighter, classic digital style with connected features. Choose a G-SHOCK if your priority is a larger, more rugged watch case.
