You can now buy the Casio Edifice EFR539D-1A2V and EFR539DE-2AV watches at the brand's online store for $155 each. On the product listing, Casio notes that there is limited stock available of each model. It states that there are three units of the EFR539DE-2AV, though the exact number of EFR539D-1A2V is not provided.

The EFR539D-1A2V has a black dial with many blue accents, while the EFR539DE-2AV has a light blue watch face with darker blue elements. Both versions have a three-dimensional bezel and are accompanied by a silver colored stainless steel band with a one-touch three-fold clasp.

These Edifice watches have three analog hands, for the hour, minute and second, and are said to remain accurate to within 20 seconds each month. There are three dials, linked to the 1/10th second stopwatch; they indicate the 1/10th seconds, seconds and minutes passed. Plus, there is a simple date display indicating the day of the month. On top of this, these timepieces are water resistant to 100 m and should run for around two years on an SR920SW battery.
