The storyWhy this reference matters
The Gentleman arrived in 2019 with a simple, difficult brief: be the watch that does everything. Forty millimetres, a clean dial, 100 metres of water resistance and a bracelet you can swap without tools. Nothing that grabs you in a photograph, and everything you need to leave it on for a week. The Silicium version is what turned that brief into a technical story, because it pushed a material that had lived several rungs up the ladder down into the entry range.
The hairspring sets the watch's rhythm, and a steel one magnetises. A handbag clasp, a speaker or a laptop lid is enough to have it gaining minutes a day; magnetism is one of the most common reasons a watch ends up on a bench. Silicon doesn't magnetise, needs no lubrication, and is etched from wafers to micrometre precision, so two hairsprings come out practically identical instead of being adjusted one by one by hand.
There is a hierarchy inside Tissot's own range and it pays to know it. The standard Powermatic 80 runs a Nivachron hairspring, a titanium alloy that shrugs off magnetism and temperature swings; the Silicium moves up to silicon, counts twenty-five jewels and adds a decorated rotor you can watch through the sapphire case back. When Tissot introduced the 38 mm Gentleman in 2026, it went back to Nivachron: silicon is still the forty's territory.

IdentificationHow to tell it apart
Forty millimetres, 11.5 mm thick, 164 grams on the bracelet. This reference has the electric blue dial with applied faceted markers, Super-LumiNova on hands and markers, and a date window in a metal frame. The steel bracelet closes on a butterfly clasp with pushers and uses Tissot's own quick-change system; the lugs are 21 mm.
To tell a Silicium from any other Gentleman, turn it over: sapphire case back, decorated rotor. A solid back means the quartz version. And if the case measures 38 mm rather than 40, it isn't this one either — that model runs Nivachron and drops to 45.7 mm lug to lug against roughly 48 on the forty.
CollectingWhat collectors check
This is a watch for wearing, not for a display case, so look at the wear. The polished centre links scratch immediately and give away the life it has had; after a thousand openings the butterfly clasp starts to wobble and pop open on its own. Hang the watch from its bracelet, open and close the clasp a few times, and decide after that.
The silicon hairspring is the reason to buy it and also the reason not to buy one blind: it leaves the factory non-magnetic, but it can't be tweaked, so if the watch runs badly there is no regulator index to nudge. Ask to see it timed on a timegrapher or an app over a couple of days in two positions, and check it really holds the eighty hours before you call it healthy.
The 21 mm lugs are the model's domestic trap. It is an odd size, decent straps are thin on the ground, and if the seller isn't including the original bracelet, price that in. Check the quick-change spring bars are there too: they go missing with astonishing ease.
Common questionsWhat people ask us about this reference
What does the Tissot Gentleman's silicon hairspring actually do?
It doesn't magnetise, it needs no lubrication, and it leaves the factory with identical geometry in every unit. In practice: fewer nasty surprises near magnets, and a rate that stays steadier over the years.
What is the difference between the Gentleman Powermatic 80 and the Silicium?
The standard model has a Nivachron hairspring and an undecorated rotor. The Silicium runs a silicon hairspring, counts twenty-five jewels and shows off a decorated rotor under the sapphire case back.
How much power reserve does the Powermatic 80 have?
Eighty hours. That is double a conventional ETA 2824-2, and it comes from dropping the frequency to 3 Hz and lengthening the mainspring.
Can you swim with the Tissot Gentleman?
It is rated to 100 metres, enough for swimming and showering as long as the crown is pushed fully home. As with any watch, the number is worth only as much as the gaskets: have them checked every few years.
