- 1 Year Warranty
The EDIFICE EFR-109D-1ADF is the quietest watch EDIFICE makes. No chronograph, no tachymeter, no sub-dials — three hands and a date on a clean face, in a stainless steel case measuring 38mm across and just 9.8mm thick. The design draws on classic sports cars rather than modern motorsport, which is why it reads as restrained where most of the range reads as technical.
The detail that gives it character is the dual-curved box crystal, domed over the dial so the markers appear to sit deeper than they are and distort slightly toward the edge. It is a vintage construction, and it is the reason this watch looks considered rather than plain. At 9.8mm it clears a shirt cuff easily, and the steel bracelet with its one-touch three-fold clasp is rated to 100 metres.

Why You'll Love It
- 9.8mm is unusually thin for a steel sports watch. It slides under a cuff rather than catching on it, which is the practical difference between a watch you wear to work and one you only wear at the weekend.
- The dual-curved box crystal domes over the dial and gives it visible depth. It is a vintage construction that most watches at this level skip, and it is what you notice first in person.
- 38mm is a classic proportion that has come back into favour. On a slimmer wrist it sits properly rather than overhanging, and the 45.3mm lug-to-lug span keeps it within the bone.
- Three hands and a date, nothing else. No sub-dials competing for space means the face stays legible at a glance and the watch moves between a suit and a weekend without changing register.
- 100-metre water resistance puts swimming and snorkelling in scope, which a dress watch this slim would not normally allow.
- Stainless steel case and bracelet throughout with a one-touch three-fold clasp, and roughly three years per battery with nothing to set beyond the date.

Frequently Asked Questions
What is a dual-curved box crystal?
The glass is domed rather than flat, curving in two directions so it stands slightly proud of the bezel like a box. Looking straight down you get a sense of depth across the dial; from an angle the markers near the edge distort a little. It is a vintage construction, and it is the main reason this watch has visual character despite a very plain face.
Is 38mm too small?
38mm is a classic proportion that suits wrists from roughly 15cm to 18cm particularly well. What determines whether a watch overhangs is the lug-to-lug span, and at 45.3mm this one sits within most wrists rather than across them. At 9.8mm thick it also clears a shirt cuff, which larger sports watches rarely do.
Can I swim with it?
Yes. 100-metre (10 BAR) water resistance covers swimming and snorkelling. It is not intended for diving. Do not operate the crown while the watch is wet.
Is the bracelet adjustable?
Yes. The stainless steel bracelet fits wrists from 150mm to 205mm and is resized by adding or removing links. City Chain offers complimentary bracelet sizing at any outlet — bring your warranty book along for the service.
How long does the battery last, and can I get it replaced?
Approximately three years on a single SR920SW cell. When it runs down, bring the watch to any City Chain outlet — having it changed by a service centre keeps the case seal correctly reseated, which protects the 100-metre rating.
How accurate is it?
±20 seconds per month, which works out to a few minutes of drift across a year. Correcting it takes a moment with the crown.
What other versions are there in this series?
The EFR-109 runs across four references sharing the same case, module and proportions. The D models — 1A, 2A and 3A — are on stainless steel bracelets in different dial colourways, and the EFR-109L-7A pairs the same case with a leather strap. Everything structural stays the same across the family.
What warranty does this watch come with?
The EFR-109D-1ADF comes with Casio's official 1-year warranty when purchased from City Chain Singapore, an authorised Casio retailer.
