Owners + reviewers, side by side

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

Owners widely praise Oak & Oscar The Olmsted ExP-01 for its exceptional finishing, comfortable bracelet, and smooth movement. The dial designs are a frequent point of admiration, with specific appreciation for the white, navy, and gray variants, as well as the orange seconds hand. The watch is considered fairly priced at around $1.5k and is noted for its versatility and "soul." On balance, owners rate Oak & Oscar The Olmsted ExP-01 highly for its overall quality, design, and the brand's customer service.

Phoibos Leviathan

Owners widely praise the Phoibos Leviathan for its excellent value, superb case finishing, and generous lume. The watch is described as visually striking, legible, and well-made, with a unique case design, sapphire crystal, and a comfortable FKM strap or excellent bracelet with a milled clasp and quick adjustments. Some owners note the bezel's staggered jimping can cause fingers to slip, and the beveled crystal can distort the view of indices. Accuracy varies, with one owner reporting losing 5-10 seconds per day without a winder, while others state it keeps accurate time out of the box. The watch is frequently described as heavy and thick, with some owners finding it too large for wrists smaller than 7.5 inches, although newer models feature an improved clasp for better comfort and functionality. Overall, owners rate the Phoibos Leviathan highly for its striking design and impressive finishing at an accessible price point.
