Tissot PRX Watch Guide
This is a supporting guide to our main Tissot Brand Guide. It focuses specifically on the PRX collection — its origins, sizing, movements, and how to choose the right model.
1 | Overview
The Tissot PRX is a modern reissue of a 1978 integrated-bracelet sports watch, redesigned for contemporary wear while retaining its original proportions and character.
Reintroduced in 2021, the PRX quickly became one of the most discussed and purchased Swiss watches in its price category. It delivers the visual language of high-end integrated sports watches — sharp case lines, flat bracelet, slim profile — at an accessible price point.
The PRX is available in quartz and automatic formats, multiple sizes, and a wide range of dial colours, making it suitable for both first-time Swiss watch buyers and experienced collectors.
2 | Origins of the PRX
The PRX design is rooted in a 1978 Tissot model featuring an integrated bracelet and slim quartz movement.
What PRX Stands For
- PR: Precise and Robust
- X: Roman numeral for 10, referencing 10 bar (100m) water resistance
The modern relaunch respects the original case shape and bracelet geometry while updating materials, finishing, and movements for modern expectations.
3 | PRX Case & Bracelet Design
The defining feature of the PRX is its integrated bracelet. Unlike traditional watches with visible lugs, the bracelet flows directly from the case, creating a single continuous form.
Integrated Bracelet
Bracelet flows directly from the case with no visible lugs. Tapered steel bracelet with butterfly clasp. This design language is typically found in luxury watches costing several times more.
Slim Profile
Flat case profile for comfortable daily wear. Brushed surfaces with polished accents. Low-profile bezel and clean dial layout. One of the best value Swiss sports watches available.
4 | Quartz vs Automatic
PRX Quartz
Battery-powered Swiss quartz movement. Ultra-slim case profile. Maximum accuracy with minimal maintenance. Ideal for grab-and-go daily wear. Lower entry price from £290.
PRX Powermatic 80
Self-winding mechanical movement. 80-hour power reserve. Nivachron hairspring (anti-magnetic). Exhibition caseback on most models. From £640 — prioritises mechanical interest and heritage.
Practical Difference
Quartz prioritises convenience; automatic prioritises mechanical interest and heritage. Both share the same iconic case and bracelet design.
5 | Dial Variations
The PRX is offered with multiple dial styles to suit different tastes.
- Sunburst dials: clean, reflective, minimal — standard on quartz models
- “Waffle” textured dials (automatic models): added depth and visual interest
- Colour options: blue, green, black, white, ice blue, and seasonal releases
Dial choice is often the deciding factor for collectors who own more than one PRX.
6 | Sizing & Fit
PRX sizing is critical because the integrated bracelet limits visual adjustment.
40mm
Traditional men's size with strong wrist presence. Recommended for 6.5–7.5 inch wrists. Modern sport proportions.
35mm
True unisex size, closest to the 1978 original proportions. Recommended for 6–6.5 inch wrists. Vintage feel.
25mm
Compact, traditionally marketed toward women. Elegant proportions on smaller wrists. Available in quartz only.

8 | Frequently Asked Questions
Is the PRX a good first Swiss watch?
The PRX is widely regarded as one of the best entry points into Swiss watchmaking. The quartz version starts at £290, offers the same iconic integrated-bracelet design as the automatic, and requires no maintenance beyond battery changes. The Powermatic 80 automatic at £640 adds mechanical heritage with an 80-hour power reserve.
Should I buy the 35mm or 40mm PRX?
The 35mm is the closest to the 1978 original and wears as a true unisex watch — ideal for 6–6.5 inch wrists or those who prefer vintage proportions. The 40mm has a stronger modern sport presence and suits 6.5–7.5 inch wrists. Try both on in-store at OD's for the best comparison.
Can I swim with the PRX?
Yes. The PRX has 100m water resistance, making it suitable for swimming and water sports. Rinse with fresh water after saltwater or chlorine exposure. Not recommended for diving.
What is the difference between sunburst and waffle dials?
Sunburst dials have a clean, reflective surface with light rays emanating from the centre — standard on quartz models. Waffle textured dials have a grid pattern that adds visual depth and is typically found on Powermatic 80 automatic models.
