## The Challenge

The GA-2100’s octagonal design has earned it the nickname “CasiOak” for its resemblance to the iconic Audemars Piguet Royal Oak. But how close does a ~$100 Casio with a $50 metal case really get to a $30,000+ luxury watch?

Let’s find out.

## 2. Design Comparison

### 2.1 Case Shape

**Octagonal Bezel:**

**Visual Impact:** From 3 feet away, the silhouette is remarkably similar. The octagonal shape is the defining visual element of both watches.

### 2.2 Dial Design

**Metal CasiOak:**
– Simple, clean dial
– Digital + analog hybrid
– Minimal text
– Standard indices

**Royal Oak:**

**Verdict:** The dial is where the difference is most obvious. The Royal Oak’s dial is a work of art; the CasiOak’s is functional simplicity.

### 2.3 Case Size

|———–|—————|—————–|
| Diameter | 48.2mm | 41mm |
| Thickness | 11.1mm | 10.4mm |
| Lug-to-lug | 45.2mm | 49.5mm |
