Casio has announced a new series of BLX-100 Baby-G watches that feature a tide graph. This new G-Lide lineup is aimed at women that like surfing and other water sports. This new design seems to be inspired by the G-7900 G-Shock series. These will be going on sale soon around the world.

Casio Releases Baby-G Watches Ideal for Water Sports
New G-Lide Watches Feature Water-Resistance up to 200 Meters and Tide Graph Function

TOKYO, January 27, 2011 — Casio Computer Co., Ltd., today announced the release of new Baby-G shock-resistant watches for women—five BLX-100 models in Casio’s G-Lide lineup, which is optimally designed for use in extreme sports. These five new models are equipped with a tide graph function and water-resistance of up to 200 meters.

The BLX-100 models are equipped with a tide graph function, which graphically displays tide levels for a specific date and time. With these features, in addition to 200-meter water resistance, the BLX-100 models are perfect for women who enjoy the thrills of surfing and bodyboarding.

The BLX-100 models are not only highly practical for water sports; their design also features reference to the ocean on every part of the watch. A wave with ocean spray is depicted inside the tide graph display. Parts of the face use a metal material to radiate like the glittering reflection of sunlight on seawater. Along with that, four protective parts, molded in a pyramid shape, have been placed around the watch face to accent the overall design of the watch.

Four models in the BLX-100 series come in colors that represent the changes throughout a day at the beach: white suggests the beach sand in the morning; blue represents the color of a beautiful sea; red symbolizes the setting sun; and black and pink signify the dreamy light of dusk. In addition, Casio is offering a special edition model finished in a striking combination of Rasta red, green and yellow. These five colorful models in the BLX-100 series are so hot they may even outshine the sun at the beach.

    200m WR has been rare in the BBG lineup, so it's nice to see the BLX100 complying to this rating. Also checked the specs on the press release page, it's quite neat IMO (basically the G8000 feature set plus tide graph function), not as beefy as the G7900's feature set, but is good enough.

    Unfortunately some color schemes are way too flashy and do hinder effective viewing. The blue, red, and yellow casings for example have barely legible "snooze/alarm/signal/mute" indicator labels. Plus the color displays (esp. tide graph section) are nothing practical but instead aesthetic, as well as too feminine. The white 7DR model is by far the neatest one, but IMO it would be wise to have an additional standard black model featuring the 7DR's normal-colored LCD display but enclosed in an all-black casing (similar to the 1DR's, but minus the pink accents).

    Riley, please update post with main specifications from the offical release page, that would be very helpful to the readers.


    Thanks for the suggestion yazkaz. :-!

    I forgot to add the specs to the original post. I just updated it with them.

    I agree with most of your thoughts on these. BTW - I had to do some color correction to the big images of each model. So those still aren't probably 100%. I don't know what caused that to happen.


    It looks like G-Street got completely messed up with the color management policies. Very likely these higher-res images were originally CMYK but were forcibly converted to RGB without implenting the correct conversion procedure. There's a way to do it, but you'll need to get access to the original files first, not the ones at G-Street.

    It's unproductive to take the G-Street's photos and tweak the color — these images have been severly damaged in terms of integrity. And without having a reference, you may even worsen it.

    Casio Japan used to include higher-res images with their press releases, but that stopped a couple years ago. The Japanese clearly stick to color management system policies more straightly than some non-professional designers/bloggers/etc. who may not understand the importance of CMS. I'd say, stick to the colors from the original release page. As for the higher-res photos, you may have to wait till Casio USA release them later — those official press images are definitly better and almost always CMYK, which means proper conversion to the web's sRGB gamut is necessary, but can be done more effectively with proper procedure.

    Back to the BLX100. Just noticed the ±30 seconds accuracy claim. Definitely not very good from my experience. A ±15s accuracy should be achieved instead. Also the specs doesn't specify the EL backlight type, is it an Auto EL type (ie. tilt 40 degrees for auto-on)? It'd better be, otherwise it won't make this model look good.


    I'll try to update the images when we get some better ones. At least you can see some more of the details in the larger ones, but these are definitely not accurate. These watches usually look different than the stock photos in real life anyway.


    Hi guys, this is Anthony from G-Street. I read the comments made about these images and thought I'd best clear things up. The larger images used in our post came directly from an official Casio press server where they were saved as high res tifs. There were no colour management changes made by us (we are not 'non-professional bloggers')… we simply used the best high-res images available. Unfortunately the colour management issues originated from Casio's end. Cheers!


    I apologize for being a bit rough, but would you mind sending these hi-res images over to me? Maybe I can take a look and see if I can do a better job matching and converting the colors, then send them back to Riley…

    BTW the official press server, does it need login/password? If not then everything is open to the public. If you can PM me the direct link to these images that would be great; otherwise, put them on web storage and send me the links.
