Why people order the F-91W in Bali
The F-91W pairs with the way you actually live in Bali — scooter rides, surf sessions, dive trips, sunset drinks. The resin case shrugs off salt air, sweat, sunscreen, and the occasional drop on the rice-paddy stairs — exactly what fashion watches cannot survive. Casio service is widely available across Indonesia: any Casio boutique can do a battery swap, strap replacement, or warranty claim while you wait.
Most of our customers ask us for this watch when they realise the smartwatch they brought from Europe will not survive the reef break — or when they see one on the wrist of a local surf instructor in Padang Padang and want one too. We deliver to Canggu, Seminyak, Ubud, Uluwatu, Sanur, Jimbaran, Nusa Dua, Amed, anywhere on the island.
Frequently asked
How much does the Casio F-91W-1 — The Original cost in Bali?
Approximate retail in Indonesia is around Rp 330.000 based on Casio boutiques and authorised online retailers. Final price depends on the outlet and current promotions — we always confirm the exact price with you on WhatsApp before purchasing.
What is the water resistance of the F-91W?
The F-91W is rated to 30-50m (splash, hand-washing). It can handle splashes, rain, and brief contact with water — but we do not recommend swimming or diving with it.
What is the battery life on the Casio F-91W-1 — The Original?
~7 years. A standard battery replacement service is available at any Casio counter in Bali for around Rp 75.000-150.000.
Are these authentic Casio watches?
Yes. We only source from authorised Casio retailers in Indonesia (Casio Boutique Beachwalk, Discovery Mall, Park 23, multi-brand watch counters at Bali Galeria) and authorised Indonesian online sellers (Zalora, Shopee Mall Casio Official, Tokopedia Official Casio). Counterfeit Casio watches — especially F-91W and DW-5600 — are extremely common in Indonesia. We never source from street markets or unauthorised resellers.
Does the F-91W come with international warranty?
Yes. Casio watches purchased through authorised Indonesian retailers come with a 1-year (G-Shock, Edifice) or 2-year (MR-G, MT-G premium models) international warranty. The warranty card is filled in by the boutique at point of sale and is honoured at any Casio service center worldwide.
What about wrist sizing — will the F-91W fit me?
The F-91W ships on a resin/silicone strap with multiple holes that fits wrist sizes from approximately 145mm to 215mm. The strap is one-size-fits-most; if it does not fit, replacement straps are widely available.
How long does delivery take?
If the reference is in stock at a Bali Casio boutique (Beachwalk, Discovery Mall, Park 23) — same-day delivery to Canggu/Seminyak/Ubud/Uluwatu. If we order from Jakarta authorised online retailers it takes 2-3 working days. Premium references (MR-G, MTG-B3000) usually ship from Jakarta and take 3-4 working days.
Can I return the watch if it does not fit or I change my mind?
Casio Indonesia retailers do not accept change-of-mind returns once the warranty card is filled in. We can negotiate a strap exchange or sizing adjustment before final purchase. For this reason we always send you a video and photos of the exact piece before we close the transaction at the boutique.
How do I pay?
Bank transfer (BCA, Mandiri), GoPay, OVO, Dana, or cash on delivery. You pay the retail price for the watch plus our flat Rp 50.000 service fee.
