What people say

Owners + reviewers, side by side

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

Sternglas Naos XL Automatik

Owners widely praise the Sternglas Naos XL Automatik as an amazing and best affordable automatic Bauhaus watch for its price. However, some owners find the 42mm case size too large, with one describing it as resembling a "flying saucer" on a 7.25-inch wrist, and another noting its unsuitability for a predominantly white dial. The Miyota movement is described as just okay. Overall, owners rate the Sternglas Naos XL Automatik highly for its value proposition as an affordable Bauhaus automatic.

Seiko Prospex Sea

Owners widely praise the Seiko Prospex Sea for its excellent lume, robust build, and value, with many highlighting the comfortable 4 o'clock crown and reliable movements. Reviewers note impressive case finishing and attractive dials, with specific models lauded for their gradient blue designs and smooth bezel actions. Accuracy figures vary, with one owner reporting +9 seconds/day after demagnetization, while others find the watches to be good first "proper" watches. Some owners find the stock rubber straps uncomfortable or the overall size substantial on smaller wrists. On balance, owners and reviewers rate the Seiko Prospex Sea highly for its combination of strong dive watch functionality and appealing design at its price point.
