For a Samsung Galaxy phone user who prefers a smaller watch, the Samsung Galaxy Watch8 Bluetooth 40 mm is a strong, well-documented option. The Galaxy Watch FE is another 40 mm model to consider. Neither is specifically a women’s watch: comfort, fit and style depend on the wearer, so compare dimensions and weight and check that your exact phone meets the watch’s requirements.
Our picks for a Samsung phone
Best documented compact option: Galaxy Watch8 Bluetooth 40 mm
Samsung lists the Bluetooth Watch8 in a 40 mm case measuring 42.7 × 40.4 × 8.6 mm and weighing 30.0 g. Its listed battery capacity is 325 mAh. These specifications make it a useful starting point if you want a smaller case; they do not guarantee a comfortable fit or a particular runtime. Samsung’s Watch8 40 mm specifications identify the Bluetooth configuration. Samsung’s 2026 interim report lists weights of 30.0 g for the 40 mm Watch8 and 34.0 g for the 44 mm model. Samsung Electronics 2026 First Quarter Interim Report.
Alternative compact option: Galaxy Watch FE Bluetooth 40 mm
The Galaxy Watch FE offers a second 40 mm choice. Samsung lists its dimensions as 39.3 × 40.4 × 9.8 mm, its weight as 26.6 g and its typical battery capacity as 247 mAh. Those figures let you compare physical size and capacity with the Watch8, but do not establish how long either watch lasts between charges. Samsung’s 2024 announcement says the FE requires Android 11.0 or later and more than 1.5 GB of memory. Samsung Global Newsroom’s Galaxy Watch FE announcement.
Consider the newer family: Galaxy Watch9
Samsung’s UK comparison catalog lists Galaxy Watch9 in 40 mm and 44 mm sizes. It is a newer family to investigate if current generation matters to you, but the catalog listing alone is not enough to make a detailed recommendation about its specifications. Confirm the exact model’s features and configuration on its product page before buying. Regional lineups may differ. Samsung’s smartwatch comparison catalog.

Compare size and battery capacity
| Model | Listed dimensions | Listed weight | Battery capacity | Connection |
|---|---|---|---|---|
| Galaxy Watch8 40 mm | 42.7 × 40.4 × 8.6 mm | 30.0 g | 325 mAh | Bluetooth |

Watch8 figures are from Samsung’s product specifications and 2026 interim report; the FE figures are from Samsung’s 2024 announcement. Samsung lists a larger battery capacity for the 44 mm Watch8 than for the 40 mm version, but capacity alone does not establish real-world battery life. The dimensions for the 44 mm version are not included in the cited specifications above, so check its product listing if those measurements matter to your fit.
Check your phone before choosing a watch
Compatibility depends on the specific watch generation and smartphone, not just on whether the phone is made by Samsung. Samsung’s compatibility table, updated September 11, 2026, gives these Android minimums and a minimum of 1.5 GB RAM for the listed series. Samsung cautions that some individual models may still be incompatible even when they meet the stated requirements. Samsung Galaxy Watch compatibility requirements.

Choose Bluetooth or LTE based on how you use your phone
Samsung lists Bluetooth and LTE as distinct configurations for some models. Bluetooth is the straightforward choice if you expect to use the watch with your phone nearby. Consider LTE only if you need mobile connectivity when your phone is elsewhere; check carrier support and availability in your region for the exact watch before choosing it. The cited product pages do not establish current prices or stock, so verify those separately.

- Pick the connection: Choose Bluetooth for phone-paired use or investigate LTE if independent mobile connectivity matters, checking carrier and regional support.
- Verify the exact listing: Check the model generation, size, connection type, regional availability and current specifications before ordering.
