Citizen Promaster Professional DivervsPhoibos Leviathan

The Citizen Promaster Professional Diver is a serious instrument with a robust technical appearance, featuring strong lines and an aggressive bezel. It utilizes Citizen's Duratect MRK and DLC coatings for scratch resistance. The BN1024-01E model offers a 300m depth rating and a sapphire crystal, with a 365-day power reserve from its Eco-Drive quartz movement. However, its large size, measuring 52.5mm in diameter and nearly 22mm thick, makes it unsuitable for everyday wear. One reviewer notes the absence of an orange minute hand, which is considered effective on other Promaster models. On balance, the Citizen Promaster Professional Diver is a highly capable, albeit massive, dive tool, with its scratch resistance and long power reserve being key strengths.

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.
