Tissot Chrono XL Classic T1166171609200: specs and what to check

Seventy-five grams

The published weight is 75.00 g, complete, on a 45.00 mm case.

That is the lightest figure Tissot publishes among the references here — lighter than the 104 g 35 mm PRX, and less than half the 180 g Seastar chronograph of almost identical diameter.

Two decisions produce it: a quartz movement instead of an automatic, and a leather strap instead of a steel bracelet.

It is also the strongest thing you can say about the watch in a listing. A buyer who has decided they want a large chronograph but has found steel ones uncomfortable is being offered exactly the answer to their problem, and the number makes the argument better than any adjective would.

Quote it.

Tissot publishes both strap halves

This is unusually generous documentation and worth using.

The strap reference is T600041655, and Tissot gives its lengths separately: 120.00 mm on the six o'clock side and 75.00 mm on the twelve o'clock side.

Almost no manufacturer publishes this, and it answers a question that otherwise requires the buyer to own the watch: will it fit?

Add the two lengths to the case and you have the total span. Compare that to the buyer's wrist circumference before shipping, in writing. A 45 mm watch on a fixed-length leather strap has no links to remove — either the holes reach or they do not, and finding out after delivery costs you a return.

Describe the strap as Tissot describes it

Read the construction line exactly: strap front, alligator-style grained cowhide; strap back, synthetic.

So the material is calf, textured to resemble alligator, with a synthetic lining. It is not alligator, and the word should not appear in your description except as part of the phrase "alligator-style", which is how the maker qualifies it.

That matters more than pedantry. Exotic leathers carry real value and, in some jurisdictions, real paperwork. Describing grained calf as alligator in a listing is a misrepresentation with consequences beyond a refund.

Inspect it the way you would any leather strap: the fold at each lug, the buckle holes where the tongue has worn through, and the keeper. The clasp here is a standard buckle, not a deployant, so the strap is being bent fully at every wearing.

Tissot does list it as interchangeable quick release at 22 mm, which is a common width — so a replacement is easy and cheap, unlike several other references in the range.

The chronograph has two functions people never test

Quartz chronograph PowerDrive on a 1.55 volt cell. The listed functions are an end-of-life battery warning, counters for thirty minutes and tenths, a centre chronograph seconds hand, and ADD plus SPLIT.

Start, stop and reset exercises none of the named features.

Run ADD: stop and restart without resetting, and confirm the count continues rather than beginning again.

Run SPLIT: freeze the display mid-timing, watch the hand hold still, then release it and confirm it jumps forward to the true elapsed time. A hand that simply resumes has failed.

And before concluding anything is broken, check the EOL indicator. A seconds hand moving in multi-second lurches is the watch reporting a flat battery, which is a cheap fix and not a deduction.

Case and dial

45.00 mm across, 11.02 mm thick, 10 bar (100 m / 330 ft), crystal listed simply as sapphire with no coating specified.

The dial is green with Arabic indexes and Super-LumiNova on the hands. Tissot publishes no bezel material and no caseback description for this reference, so report what you observe on the watch and label it as your own observation.
