What Size is Galaxy Watch 8 Classic?

Name: Google Pixel Watch 4
Brand: Google
Availability: PreOrder
Rating: 4.8 (1250 reviews)

The Galaxy Watch 8 Classic comes in a single 46mm size only. Unlike the standard Galaxy Watch 8 which offers 40mm and 44mm options, the Classic is exclusively available in the larger 46mm size.

Dimensions

Specification	Measurement
Case Diameter	46mm
Thickness	10.6mm
Weight	86g
Band Width	22mm

Why Only 46mm?

The Classic's single size is due to design priorities:

Rotating Bezel: The physical bezel mechanism requires adequate space for the mechanical components
Traditional Aesthetics: Larger size mirrors traditional luxury watch proportions
Premium Positioning: Substantial presence reflects the premium pricing and materials

Is 46mm Right for You?

46mm works well for:

Wrist circumferences above 160mm
Those who prefer a substantial watch presence
Easier rotating bezel operation (more grip area)
Traditional watch aesthetics

Consider the standard model if:

You have a smaller wrist (under 160mm)
You prefer more compact, lightweight watches
You want the 40mm option for subtle appearance

Size Comparison

Model	Size	Thickness	Weight
Galaxy Watch 8	40mm	8.6mm	~29g
Galaxy Watch 8	44mm	8.6mm	~33g
Galaxy Watch 8 Classic	46mm	10.6mm	86g

The Classic is 2mm thicker than the standard models due to the rotating bezel mechanism.

Band Compatibility

The 46mm Classic uses 22mm standard bands. This gives you access to:

Official Samsung bands (sport, leather, metal link)
Third-party 22mm bands from any manufacturer
Quick-release mechanism for easy swapping

No Size Choice

Unlike previous Classic generations that offered 42mm and 46mm options, the Galaxy Watch 8 Classic is only available in 46mm. If you need a smaller size, consider the standard Galaxy Watch 8.
