What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Erebus Watches Ascent 40 GMT

Owners widely praise the Erebus Watches ASCENT for its stunning dial and excellent lume, with many finding it gorgeous and beautiful beyond comprehension. The watch is also noted for its comfortable wearability, attributed to its 40mm case, and the bracelet's micro-adjustable clasp and well-finished screws receive specific commendation. Some owners consider the Miyota 9075 movement excellent for the price, with one reporting accuracy of +1 second per day. However, import duties are a significant concern for some buyers, and the polished case sides are noted to lack a scratch-resistant coating. On balance, owners rate the Erebus Watches ASCENT highly for its aesthetic appeal and comfortable wearability at its price point.

Spinnaker Dumas Automatic

Owners widely praise the Spinnaker Dumas Automatic for its attractive textured blue dial, applied indices, and well-finished case, noting its comfortable wearability due to a short lug-to-lug distance. Some owners flag the use of mineral crystal instead of sapphire and a bracelet with a learning curve and loose keeper. Overall, owners rate the Spinnaker Dumas Automatic highly for its aesthetics and case finishing at its price point.
