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

Physical footprint

Watch B

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. Non-round silhouettes use a verified family shape and catalog dimensions where available; missing case height or width is estimated from a conservative family aspect ratio.

1 field is excluded from the differences view because one watch lacks comparable data. Use “All specs” to inspect those gaps.
Tissot PRX and Tissot Seastar 1000 can overlap on price or use case, but the buying decision usually comes down to water-ready utility versus dressier everyday wear, sports character versus diver versatility. They both touch the sports use case, so smaller spec differences can matter more than brand preference.
Bottom line
Tissot Seastar 1000 is the more capable only watch because its 300m water resistance, screw-down crown, rotating bezel, and conventional lugs support harder daily use. Choose Tissot PRX when the slimmer integrated-bracelet design is more important than dive capability.

Tissot PRX is a better fit for low-maintenance daily wear, sports styling.
Choose Tissot Seastar 1000 when
Tissot Seastar 1000 is a better fit for low-maintenance daily wear, diver styling.
Movement and upkeep
Tissot PRX: quartz movement
Tissot Seastar 1000: quartz movement
Both use the same movement type, so maintenance differences are limited and fit or feature details should decide the purchase.
Size and wearability
Tissot PRX: 40mm · L2L 44.6mm · 130g
Tissot Seastar 1000: 40mm · L2L 47mm · 134g
Their size profiles are relatively close, so fit comes down to shape, weight, and how each watch sits on your wrist.
Water resistance
Tissot PRX: 100m
Tissot Seastar 1000: 300m
Water resistance is a meaningful separator here — the higher-rated option gives more flexibility for swimming or rougher daily use.

Tissot PRX: $375
Tissot Seastar 1000: $393
These two often land in a similar price band — which usually means fit, features, and current deal quality matter more than the sticker price.

Tissot Seastar 1000: diver
Tissot PRX leans more sports, while Tissot Seastar 1000 pulls toward diver use case — pick the one that matches how you will actually wear it.
Crystal and materials
Tissot PRX: sapphire crystal · steel
Tissot Seastar 1000: sapphire crystal · steel

Tissot PRX — it is 44.6mm lug-to-lug versus 47mm, and lug-to-lug is what decides whether a watch overhangs a smaller wrist.
Tissot Seastar 1000 — it is rated 300m versus 100m. Both are in the same broad bracket, so treat this as a tiebreaker rather than a deciding factor.
Tissot PRX is the value pick at roughly $18 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.
