Update | Casio debuts five colorful watches with transparent dials inspired by a 1970s Seiko classic

At least two models are now available for pre-order in the UK for £85 through Casio's website. We've updated the article to reflect that change.

Edited article continues as follows:

Casio’s new MTP collection is officially here after being shown off in a leak late last month, and it’s here to prove that affordable watches don’t have to look boring. With a design that takes cues from the 1970-era Seiko Time Sonar, the new Casio MTP-E740 is one of the more fun watches to come out from Casio’s August drop. 

The collection is now up on Casio's international website and consists of five models: bright orange MTP-E740-4AV, teal MTP-E740-3AV, bright blue MTP-E740-2A2V, navy blue MTP-E740-2A1V, and brown MTP-E740-1AV. The main attraction here is the translucent dial, which lets you peek at the day and date wheels underneath. It's what separates the new lineup from Casio's standard day-date offerings that hide the calendar mechanism. Here, Casio turns it into part of the design, giving the watches a playful layered look that's rarely seen on entry-level offerings. It's a neat throwback to Seiko's vintage Time Sonar models.

The day wheel has options for both English and Spanish, while a framed date window sits at 3 o'clock. The rest of the package is a familiar story, with the watch featuring a three-hand analog display, applied baton hour markers, and a 39.8mm stainless steel case and bracelet with a three-fold clasp.

The watch also boasts 50 meters of water resistance, mineral glass, and a Casio 5339 quartz movement rated to within ±20 seconds per month. Power comes from an SR920SW battery that's expected to last around three years.

As mentioned earlier, all five Casio MTP-E740 models are now listed on Casio International.

Casio has yet to confirm pricing and availability for other markets, but we expect the new watches to begin rolling out globally in the coming weeks.
