Materials
Steel, titanium, ceramic, sapphire, acrylic, lume, coatings. These pages compare what each material does on the wrist rather than on a specification sheet: what scratches, what shatters, what can be repolished, what fades, and where the marketing outruns the metallurgy.

Guides
Dials, hands and legibility
How dials are made and finished, what every hand style is called, and the geometry that decides whether a watch is actually readable at a glance.
How a watch is actually made
Ebauches, CNC cases, pad-printed dials and casing up in a clean room. How watches are really produced, who supplies whom, and where the retail price goes.
How to read a watch specification sheet
A line-by-line decode of a watch spec sheet: what each figure means, what a good value looks like, where it misleads, and what an omission tells you.
Magnetism: the most common cause of a fast watch
Why magnetized hairspring coils make a watch gain time, which everyday objects are strong enough to do it, and how to test and fix it in seconds.
Movement finishing: what you are actually paying for
Anglage, black polishing, Cotes de Geneve and perlage explained, with how to tell hand finishing from machine work through a caseback at any price.
Sapphire, mineral and acrylic crystals
Sapphire resists scratches, acrylic resists shattering and mineral glass sits between them. How the three compare on hardness, impact, optics and repair.
Shock resistance and everyday durability
What breaks when a watch is dropped, how Incabloc and KIF shock settings work, what ISO 1413 tests, and which everyday activities damage watches.
Straps and bracelets: a practical guide
Bracelet types, leather, rubber, mesh and NATO compared on comfort, water tolerance and formality, plus how to change a strap without scratching the lugs.
Swiss made, and what origin marks really mean
What the Swiss made ordinance actually demands since 2017, how Swiss movement and Swiss parts differ, and which certifications genuinely test a watch.
Watch case materials compared
Steel, titanium, ceramic, bronze, gold and coatings compared on weight, hardness, corrosion resistance and how well each one survives a repolish.
Watch lume: how it works and why it fades
How luminous dials work, why modern lume needs charging, why old tritium dials barely glow, and what to expect from tritium tubes and Super-LumiNova.
Watch marketing claims, decoded
In-house, Swiss made, chronometer, anti-magnetic, surgical grade steel. What each claim is allowed to mean, which are regulated, and what to ask next.
Brands
Casio
How G-Shock shock resistance is built and tested, why module construction changes repair economics, what solar and Multi-Band 6 fix, and where resin fails.
Sinn Spezialuhren
Sinn names a document behind almost every claim. What Ar-dehumidifying, tegimented steel and DIN 8306 certification actually do, and what Sinn does not make.
Compare
316L vs 904L stainless steel
904L carries more chromium, nickel and molybdenum than 316L, so it resists corrosion better and costs far more to machine. On a wrist, the gap is small.
NATO vs leather vs metal bracelet
Security, water tolerance, comfort and cost compared for the three ways to attach a watch to your wrist, plus how to size each one.
Sapphire vs mineral vs acrylic crystal
Sapphire resists scratches, acrylic resists shattering, mineral glass sits between and costs least. Which failure mode you would rather live with.
Super-LumiNova vs tritium tubes vs LumiBrite
Two lume mechanisms, three trade names. Which glows brightest at midnight, which still glows at 4am, and which one is quietly running out.
Titanium vs stainless steel watch cases
Titanium is roughly 40 percent lighter, warmer on skin and better in salt water. Steel is harder, cheaper to refinish and easier to sell. How to choose.
Prices
Watch strap and bracelet costs
What straps and bracelets cost in US dollars: NATO, leather, rubber and metal price bands, spring bars and tools, bracelet sizing fees and the integrated bracelet trap.
Problems
My watch irritates my skin
Nickel allergy, friction and trapped moisture produce three different rashes with three different fixes. How to tell them apart before you replace the watch.
Rust and corrosion on a watch
Rust inside a watch does not stop on its own, and the repair bill climbs every week. What to do in the first hour, and why rice is not one of the steps.
The bracelet rattles, or it has stretched
A stretched bracelet has not stretched. The pins and the holes they run in have worn, joint by joint. How to check it, and what a rebuild really costs.
The crystal is scratched
What can be polished and what must be replaced, by material. Plus the misdiagnosis behind most scratched sapphire: it is usually the anti-reflective coating.
The strap keeps breaking
Most watches that fall off a wrist lose a spring bar, not a strap. Why fat bars and drilled lugs matter, and what to replace long before it ever fails.
Tools
Strap and lug width finder
Find the right watch strap: lug width, buckle size, spring bar thickness and the strap length for your wrist.
