Side-by-side comparison of specifications and features
Compare visual case presence and physical footprint on one shared wrist. Measure your top-down wrist width for a stronger result; lug-to-lug is used when the catalog has it.
Medium (6.7″)
Estimated top width: 56.7 mm
Preliminary range: 54.7–61.8 mm.
Watch A
Visual presence
ModerateCase covers 64% of your modeled wrist width.
Physical footprint

Watch B
Visual presence
BoldCase covers 71% of your modeled wrist width.
Physical footprint

Proportional guide only: visual presence and physical footprint do not predict comfort. Weight, thickness, caseback shape, rigid lugs, strap stiffness, wrist-bone prominence, wearing tension, bezel design, and case curvature change how a watch actually wears.

3 fields are excluded from the differences view because one watch lacks comparable data. Use “All specs” to inspect those gaps.
Tissot Seastar and Zelos Mako can look close on a spec sheet, yet the tradeoffs that matter most are usually mechanical feel versus low-maintenance convenience, wrist presence versus easier fit. They both touch the diver use case, so smaller spec differences can matter more than brand preference.

Fit is a real separator here — compare case width and lug-to-lug before deciding, especially if wrist comfort matters more than headline features. Choose Tissot Seastar if you want a smaller case footprint on the wrist; choose Zelos Mako if you prefer more dial presence and a larger case feel.

Tissot Seastar: 36mm · L2L 42mm · 114g
Zelos Mako: 40mm · L2L 46mm

Water resistance
Tissot Seastar: 300m
Zelos Mako: 300m
Water resistance is similar on paper, so focus on fit, features, and price instead.
Price and value
Tissot Seastar: $355
Zelos Mako: $529
There is a real price gap here — treat the more expensive option as an upgrade decision and confirm whether the extra spend buys something you will notice in weekly use.

Zelos Mako: diver
Both lean into a similar diver use case — the choice is more about fit, features, and price than category.
Crystal and materials
Tissot Seastar: sapphire crystal · steel

Quartz and solar models are usually easier for grab-and-go use, while automatic and manual watches appeal more to buyers who enjoy the mechanical side of watch ownership.
Tissot Seastar — it is 42mm lug-to-lug versus 46mm, and lug-to-lug is what decides whether a watch overhangs a smaller wrist.
They are rated the same, so water resistance will not decide this. Choose on strap material and how much you mind scratching the case.
Tissot Seastar is the value pick at roughly $174 less. Pay more only if a specific difference above matters to you — otherwise the cheaper one is the smarter buy. Confirm live listings, since marketplace pricing moves.
