Why it's interesting
The Edifice most people picture: a big steel chronograph with a black numbered bezel, three silver-ringed registers and a 1/10-second quartz stopwatch, sold for less than many brands charge for a leather strap. Unsubtle in the best motorsport tradition, and very hard to argue with at the price.

Verified specifications, checked September 2026
Dimensions, water resistance, movement and crystal were checked against the sources below.
Case 48.5 × 43.8 × 11.6 mm, 149 g, mineral glass, 100 m, 1/10-second stopwatch, ±20 s/month and SR920SW cell from Casio's Hong Kong online flagship store (casio.com returned 403). Module 5345 per Helveti and Holland Watch Group (both list it), consistent with Casio's 5345 operation guide, whose dial layout matches this watch. Lug width 22 mm from Holland Watch Group. Launch year left blank: the HK store's 'Dec 2019' is a listing date, and the 5345 guide dates from 2013. The fixed bezel is printed 10…60 with '60' at the top; the renderer's dive bezel adds a triangle at 12 instead.
