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

The Seiko Prospex Sea is widely praised for its excellent value, solid build quality, and comfortable wearability, with many models featuring impressive lume and attractive dials. Owners and reviewers highlight the modern upgrades on classic designs, such as drilled lugs and reliable movements with hacking and hand-winding capabilities. Some models are noted for their refined case finishing and scratch resistance. Accuracy figures vary, with one owner reporting approximately 4 seconds fast per day, while others find the movements offer good performance for the price. Concerns raised by owners and reviewers include clasps that can feel generic or cheap, and lug widths that some find disproportionate to the case size on certain models. The thickness and weight of some Prospex Sea watches are also noted as substantial. The GMT function on specific models is considered secondary and difficult to read for true travel purposes.
