Galaxy Watch 6 Classic vs Galaxy Watch 5 - Upgrade Guide

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

The biggest reason to upgrade from Galaxy Watch 5 to Galaxy Watch 6 Classic is the return of the physical rotating bezel. The Watch 5 doesn't have one; the Watch 6 Classic does. Beyond that, you get a faster processor, more RAM, larger display, and premium stainless steel construction.

Key Specifications Comparison

Specification	Galaxy Watch 5	Galaxy Watch 6 Classic
Rotating Bezel	No	Yes (120-step)
Processor	Exynos W920	Exynos W930 (+18% faster)
RAM	1.5GB	2GB
Display	1.2" / 1.4"	1.3" / 1.5" (+8%)
Material	Armor Aluminum	Stainless Steel
Sizes	40mm, 44mm	43mm, 47mm
Weight	28.7g / 33.3g	52g / 59g
Software	WearOS 3.5, One UI 4.5	WearOS 4, One UI 5
Price (Launch)	$279 / $309	$399 / $429

What You Gain Upgrading

Physical Rotating Bezel: 120-step tactile navigation. Works with gloves, wet hands, and keeps your screen fingerprint-free.
Faster Performance: Exynos W930 is 18% faster with improved power efficiency. 2GB RAM means better multitasking and smoother app switching.
Larger Display: About 8% more screen area with 20% thinner bezels.
Premium Materials: Stainless steel construction feels more substantial and durable than aluminum.
Enhanced Software: WearOS 4 with One UI Watch 5 brings improved sleep coaching, full watch backup/restore, and interface refinements.

Same Health Sensors

Both watches have identical Samsung BioActive sensors with ECG, blood pressure, body composition, and SpO2 monitoring. Health tracking accuracy is essentially the same.

What You Trade Off

Weight: The Classic is 52-59g versus 28-33g. That's nearly double the weight.
Size Options: No 40mm equivalent. The 43mm Classic is slightly larger than the 44mm Watch 5.
Price: $100+ more expensive for the rotating bezel and stainless steel.
Comfort: The heavier weight may be less comfortable for sleep tracking or all-day wear.

Should You Upgrade?

Upgrade to Watch 6 Classic if:

You miss or want the rotating bezel
You want premium stainless steel construction
Your Watch 5 is showing wear after years of use
You value traditional watch aesthetics

Keep your Galaxy Watch 5 if:

You prefer lightweight watches
Touch navigation works fine for you
Budget is a concern
Your current watch still works well

For Watch 5 Pro Owners

The Watch 5 Pro has a 590mAh battery and titanium construction. The Watch 6 Classic trades that extended battery life for the rotating bezel. Consider whether the bezel is worth the battery life reduction.
