What people say

Owners + reviewers, side by side

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

Sternglas Tachymeter 2.0

The Sternglas Tachymeter 2.0 is widely praised for its upscale feel and value, featuring a Seiko TMI VK63 meca-quartz movement and a refined case with polished and matte surfaces. Reviewers note improvements over the predecessor, including better lume and the addition of Arabic numerals, while the dial offers more color and distinct sub-dials. One owner points out that the "orange" accent is actually yellow and suggests the tachymeter scale could be more functional. Overall, owners and reviewers rate the Sternglas Tachymeter 2.0 highly for its balanced design and strong value proposition as a quartz chronograph.

Timefactors PRS-40

Owners widely praise the Timefactors PRS-40 for its unique, "badass" and rugged, futuristic design, with many highlighting the 12 o'clock crown as a distinctive and appreciated feature. The bead-blasted finish is noted to show light marks but resists deep scratches, and the sapphire crystal is considered good. While some owners find the 40.2mm case size acceptable, others describe the watch as large and wearing big, though it is noted to wear thinner than an automatic version. The fixed lugs necessitate the use of NATO straps, and the included strap is well-regarded. On balance, owners rate the Timefactors PRS-40 highly for its distinctive, bombproof design and unique crown placement at an accessible price point.
