Tissot PR 100 Sport Chic T1019101135100: specs and what to check

No battery warning on this one

Several Tissot references documented on this site list an EOL function — the movement changes the seconds hand's behaviour to announce a dying battery.

This page does not list one. The movement is given simply as quartz three hands with a 1.55 volt battery and a date.

That absence is worth holding onto, because it inverts a diagnosis.

On a watch with EOL, a seconds hand jumping in multi-second steps is information: the battery is nearly flat. On a watch without it, the same behaviour is not a designed signal, so you cannot conclude anything from it.

The practical rule here is to measure the cell rather than interpret the hands. And when a buyer reports odd behaviour, do not reassure them it is "just the battery indicator" — this reference does not have one.

The clasp is the only closure

The bracelet is T605042083 at 18.00 mm, closing with a folding clasp with push-buttons. No safety lock is listed, and no quick-release option either.

So the clasp is the single thing holding a 112-gram watch on a wrist, with no secondary catch behind it.

Check it properly. Press both buttons and confirm they release evenly. Close it and confirm it snaps rather than merely resting. Then take hold of the bracelet either side of the closed clasp and try to rock it: any play you can feel is worn hinge pins, and worn pins on a folding clasp get worse rather than better.

Hold the bracelet horizontally from one end and look for droop. Eighteen millimetres is a common enough width that a replacement bracelet or strap is easy to find — but the absence of quick release means a change needs spring bars and a tool.

Nine millimetres has nowhere to hide

The case is 9.00 mm thick on a 36.00 mm diameter — the thinnest and smallest combination among the Tissot references here.

Thin cases are unforgiving to inspect. There is very little case flank, and what there is tends to be polished rather than brushed, so every mark sits on a mirror surface with no satin texture to break it up.

Take the watch to a window, angle it so a straight edge reflects along the side, and follow the reflection round. You are looking for the fine haze of accumulated handling as much as for individual scratches — on a small polished case, haze is what actually determines how the watch photographs.

Say what you find. A buyer looking at a 36 mm dress-sport watch is buying its neatness, and neatness is exactly what surface haze removes.

The rest of the sheet

36.00 mm wide and long, 112.00 g complete. The rating is 10 bar (100 m / 330 ft), and since Tissot describes nothing that screws down, it holds only while the crown is pressed fully in.

The crystal is sapphire, coated on the underside alone. Tip it under a lamp and look for bloom trapped behind the glass, which no polish will reach.

Dial blue, index markers, Super-LumiNova on the hands. Bezel stainless steel.

Tissot publishes no caseback line for this reference. Describe whatever the watch actually carries, and mark that sentence plainly as something you looked at rather than something the maker stated.

One last confirmation while the watch is in front of you: watch the seconds hand. It should step once per second. If it sweeps, you are not holding the reference this page describes.
