Review: F91とA158を持っているのですが、暗闇では見にくいです。 手元にあるDW-5600E（FOXFIRE）は2023年6月にdesertcart Japanで購入。2023年12月にモデルチェンジしていたことを最近知りました。 後継機のDW-5600UEはELではなくなりました。LED。 「G-Shock」「Baby-G」は現行モデル全てが、ELではなくなり、LEDとなっていました。 CASIO Japanの公式サイトでよく確認してみたのですが、「G」ではない安価モデルで、F105とA168のみ、まだELでした。 CASIO最後のELモデルがF105とA168。 という訳で、両方とも購入してみました。 結果は大満足。 F91やA158、A159等とはバックライトが異なります。 ELは非常に見やすいです。 F105とA168はおすすめです。 Review: It is slightly thicker than the F91W, but light functionality is way better. ## Features - H 1.5 x W 1.4 x D 0.4 inches (39.0 x 35.4 x 9.6 mm); Weight: 0.7 oz (21.0 g); Maximum arm circumference 7.9 inches (20 cm); Min: 5.7 - Resin (case), Resin (strap) - Digital, Waterproof for Everyday Use, EL Backlight, Stopwatch (1/100 second, 60 minutes), Alarm, Hourly Signal, Auto Calendar, 12/24-hour Display Switching, Color: LCD (Dial), Black (Strap) - Box, warranty card, instruction manual (English language not guaranteed) - 1 Year ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000GB1RAU | | ASIN | B000GB1RAU | | Additional Features | Alarm | | Age Range Description | Adult | | Amazon Bestseller | #101,919 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #675 in Men's Wrist Watches | | Band Color | Black | | Band Material Type | Resin | | Band Width | 18 Millimeters | | Bands | 1 | | Batteries | 1 Lithium Metal batteries required. | | Brand Name | Casio | | Case Diameter | 35 Millimeters | | Case Material Type | Stainless Steel | | Case Thickness | 10 Millimeters | | Clasp Type | Buckle | | Closure Type | Buckle | | Crystal | Acrylic | | Customer Reviews | 4.6 4.6 out of 5 stars (3,143) | | Date First Available | October 25, 2011 | | Department | Men | | Dial Color | Gray | | Display | Analog-Digital | | Embellishment Feature | Crystal | | Face Style | Eliminator | | Included Components | 1 x Waterproof Strap | | Is Discontinued By Manufacturer | No | | Item Weight | 21 Grams | | Item model number | F105W-1OS | | Manufacturer | CASIO(カシオ) | | Manufacturer | CASIO(カシオ) | | Manufacturer Part Number | F-105W-1A | | Model Name | Illuminator | | Model Number | F105W-1OS | | Pattern | Solid | | Power Source | Battery Powered | | Product Dimensions | 11.81 x 8 x 5.59 cm; 21 g | | Shape | Round | | Sport Type | Walking | | Strap Type | Two piece straps | | Style Name | Belt Type | | Theme | Boatting | | UPC | 079767542085 | | Watch Movement Type | Quartz | | Water Resistance Depth | 300 Feet | | Water Resistance Level | Water Resistant | ## Images ![Casio F105W-1A Casio Illuminator Watch - Image 1](https://m.media-amazon.com/images/I/51GUx+NFHgL.jpg) ![Casio F105W-1A Casio Illuminator Watch - Image 2](https://m.media-amazon.com/images/I/61l9+8LJh8L.jpg) ![Casio F105W-1A Casio Illuminator Watch - Image 3](https://m.media-amazon.com/images/I/81j28zvmrdL.jpg) ## Questions & Answers **Q: Does it beep hourly?** A: Hello,Thank you for contacting us about our products.
