5.0 out of 5 stars Very stylish and great price
Verified PurchaseI bought this watch for my 10 year old girl. I would say that based on the strap size, it would be too big for a younger child. It looks fantastic. Very stylish and very retro at the same time. My little girl has lost her smart watch, so I was unsure how she would take to this, but she really likes it. It's fantastic in the respect it teaches the kids the 24 hour clock if necessary. Very pleased.

5.0 out of 5 stars Il leggendario Casio F-91W ma rosa!
Verified PurchasePreso per regalarlo alla mia fidanzata che mi chiede sempre l'ora. Molto bello in questa colorazione rosa con cinturino rosa/trasparente.
L'orologio in sé è un modello ormai leggendario della Casio che ben conosco in quanto possessore di quello dalla colorazione più classica (nero). Un modello leggero, pratico e anche stiloso. Resiste all'acqua, alle botte e la batteria dura almeno un decennio.
Ottima idea regalo in quanto assai particolare poiché nei negozi fisici non l'ho mai visto di tal colore.

Laura SepulvedaReviewed in Mexico on July 19, 2025
5.0 out of 5 stars Hermoso tono de rosa.
Verified PurchaseEs el clásico casio f91WS pero rosita y con la correa rosa "transparente." ¡Me encantó! Super sencillo de usar, no pesa. Es el reloj que necesitas para ver la hora y verte bien. El único pero que le pongo es que la luz es muy bajita (típica de este modelo) y su protección al agua es muy básica (solo protección tipo lluvia ligera o alguna que otra gota de agua). Dejando lo negativo, es un reloj de uso diario, (salvo si te agarra una lluvia fuerte) y se ve hermoso.
Laura SepulvedaHermoso tono de rosa.

5.0 out of 5 stars casio siempre será la mejor opción
Verified PurchaseThe media could not be loaded.
lo único “malo” que podría objetar sobre el reloj es la luz de noche, está ubicada en la parte izquierda del reloj y solo se alumbra en ese lado pero por el resto es genial, dejo fotos y vídeos del reloj por si alguien más está indeciso de si pillarlo o no, espero que os resulte útil.
por cierto, el reloj suena siempre a y punto jajaja así que por las noches os aconsejo meterlo en algún sitio para que no lo escuchéis cada hora al dormir 😅
