If you are buying a Tag Heuer Aquaracer replica, the first fork in the road is not colour or strap — it is 300m or 500m. The two divers look like cousins but serve different wrists and different use cases, and picking wrong means a watch that is too big (or not "right") for how you actually wear it. Here is the side-by-side, based on the 62 references in our Aquaracer replica collection.
Quick answer
Wrist under ~17cm, or you want a daily watch you can also wear to the office → Aquaracer 300 (40mm). Wrist ~17–20cm, or you want the classic big diver look and plan to actually swim in it → Aquaracer 500M (43mm). Both are available as replicas on this site; the difference is proportions and intent, not quality.
The two models side by side
| Spec | Aquaracer 300 (40mm) | Aquaracer 500M (43mm) |
|---|---|---|
| Case diameter | 40mm | 43mm |
| Rated depth | 300m | 500m |
| Original movement | Calibre 5 (automatic) | Calibre 11 (automatic) |
| Bezel | 120-click unidirectional, slim profile | 120-click unidirectional, larger ceramic/composite options |
| Best for | Daily wear, smaller wrists, dressier contexts | Serious diving look, larger wrists, sport contexts |
Note: replica listings on this site use their own movement sourcing — some Aquaracer replicas run Swiss automatic, some Swiss quartz — and each listing states exactly which one ships. The "300/500" names refer to the design you are buying, and the water-resistance rating of the original that design is based on.
Which one for which use case
Daily driver, office to gym
The 40mm 300 is the easier all-day watch. It slides under a shirt cuff, it is lighter, and the slimmer bezel makes it read as a sport watch rather than a tool watch. If this is your first TAG replica and you are not sure, start here.
Pool, sea swimming, water sports
Either works — 300m and 500m are both far beyond recreational swimming. Choose by wrist size, not by metres. What matters for water use is the gasket and crown condition, which is why we recommend a water-resistance check after the first year of regular wet use (see our Water Resistance & Care page).
The "I want the big diver" buyer
The 43mm 500M is the statement piece: larger lume plots, bigger bezel numerals, the proportions people photograph. On a 17cm wrist it will overhang; on 18–20cm it is exactly right. If you are between sizes, measure your wrist first — it takes two minutes and saves a return.
What "100m water resistance" on our listings means
Some Aquaracer-style replicas on this site are rated 100m rather than 300/500m — typically the quartz references with a different case construction. 100m means rain, washing hands, swimming and snorkelling are fine; it does not mean pressure diving. The rating is stated per listing, and the Water Resistance & Care guide explains what each rating does and does not cover, plus how to keep a gasket healthy.

Bottom line
300 vs 500 is a wrist-size and intent question, not a quality question. Measure your wrist, decide how the watch will actually be used, then pick the reference in the Aquaracer collection whose listing matches — movement, crystal and water resistance are all stated per reference. Shipping from Guangdong runs 10–20 days (details), and warranty terms are in the FAQ.
