What people say

Owners + reviewers, side by side

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

Boldr Rally

Owners widely praise the Boldr Rally's compact 38mm titanium case and excellent value under A$500. The VK64 mecaquartz movement has proven reliable for years, and the sapphire crystal is a welcome feature. Some owners find the dial busy and difficult to read, particularly the black hands against the black subdial, and note the bead-blasted titanium case can be a scratch magnet. The default straps have been described as boring or not holding up to daily wear. Overall, owners rate the Boldr Rally highly for its robust titanium construction and excellent value, despite some legibility concerns.

From video reviewers

The 38mm titanium case with a 44mm lug-to-lug measurement provides a comfortable and compact fit. The 200m water resistance is noted as robust for a chronograph. The 14mm thickness was mentioned as potentially substantial for the watch's size.

Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its refined, slimmed-down 39.5mm stainless steel case with a "super hard" coating and a box-shaped sapphire crystal. It offers 200 meters of water resistance and is powered by the slim Caliber 6L37 automatic movement, which has a 46-hour power reserve and an accuracy rating of -10/+15 seconds per day. Reviewers highlight its wearability and functionality as a dive watch, with one noting it as Seiko's thinnest diver ever at 12.3mm. However, concerns are raised about Seiko's continued reliance on the 62MAS design, with one reviewer wishing the Marinemaster remained a separate line, and the bracelet's end-links appearing mismatched in initial images. Its price of A$4,650 is considered high given its specifications compared to competitors.
