Purify Time is SurLuster’s glass-coating watch cleaner, built from the same technology used in car care. Learn what it does, which materials it’s safe for, and how to use it.
If you own a mechanical watch, a dive watch, or any timepiece made of metal, ceramic, or glass, you’ve probably faced the same problem car owners face with their paint: fingerprints, sweat, dust, and micro-scratches build up over time and dull the finish. SurLuster’s answer is Purify Time — a watch-care spray that applies the brand’s automotive glass-coating technology to something much smaller than a car.
It’s a simple product, but an unusual one: a car care company making a watch cleaner. Here’s exactly what it is, how it works, and when you should reach for it.
What Is Purify Time?

Purify Time (product code S-136) is a 30mL spray-on cleaner and coating designed specifically for watches — the metal case and bracelet, and the glass or crystal face. It comes with a dedicated cloth: spray the cloth, wipe the watch, and you’re done. No water, no disassembly, no soaking.
What makes it different from a standard jewelry or watch cloth is what happens after the wipe. Purify Time doesn’t just lift dirt and oils off the surface — it leaves behind a glass-based hybrid coating, the same category of finish SurLuster uses in its automotive coating line. That coating adds shine, helps the surface resist fingerprints and dust going forward, and provides a small amount of protection against fine surface scratches.
How It Works: Glass-Based Coating + Antistatic Protection
Purify Time is built around two active ingredients working together:
- 1. Glass-based special silicone (hybrid coating) This is the same coating chemistry family used to protect car paint from swirl marks and environmental grime. On a watch, it cleans the surface and forms a thin protective film in the same motion — so cleaning and coating happen in one wipe, rather than two separate steps.
- 2. Antistatic agent Static electricity is a known enemy of precision instruments — it attracts dust and can interfere with sensitive components. Purify Time includes an antistatic agent specifically to reduce static buildup on the watch surface, which helps keep dust from resettling right after you’ve cleaned it.
The result is a watch that’s not just wiped clean, but left with a light protective layer that makes the next cleaning easier too.
What Materials Is It Safe For?
Purify Time is formulated for the hard, non-absorbent materials most watches are made of:
- Stainless steel
- Steel
- Gold
- Silver
- Ceramic
- Carbon
- Titanium
- Aluminum
- Glass (watch crystals)
This covers the vast majority of watch cases, bracelets, and crystals on the market — from everyday stainless steel sport watches to titanium and ceramic dive watches.
What NOT to Use It On
Purify Time is not safe for absorbent materials, including:
- Fabric straps (NATO straps, canvas, etc.)
- Leather straps (including synthetic/faux leather)
Because these materials soak up liquid rather than repelling it, applying a coating product to them can cause staining or discoloration. If your watch has a leather or fabric strap, clean the case and bracelet only, and keep the spray away from the strap material.
When Should You Use Purify Time?

Purify Time fits naturally into a few situations:
- Routine maintenance — a quick wipe every couple of weeks keeps metal and glass free of fingerprints, oils, and dust buildup.
- After heavy wear — sweat from exercise, humidity, or a long day can leave residue on the case and bracelet; wiping it down helps prevent buildup in the links and clasp.
- Before storing a watch — if you’re rotating watches or putting one away for a while, a light coat helps keep the surface protected and dust-resistant while it sits unworn.
- When a watch looks dull rather than dirty — if regular wiping isn’t restoring shine, that’s usually a sign it’s time for a coating refresh, not just a cleaning.
It’s not meant for deep cleaning debris out of case seams or bracelet links — for that, follow your watch manufacturer’s cleaning guidance first, then use Purify Time as the finishing step.
How to Use Purify Time (Step by Step)

- Test first. Apply a small amount on an inconspicuous area of the watch to confirm there’s no adverse reaction.
- Shake the bottle well, then spray an appropriate amount onto the included cloth — not directly onto the watch.
- Spread it evenly over the case, bracelet, and crystal using the cloth.
- Wipe with the dry part of the cloth immediately. Don’t let the liquid sit — leaving it too long can cause staining or uneven marks.
- Wipe carefully around gaps and links (clasp, bracelet joints) so liquid doesn’t pool in small crevices.
- If white residue remains, buff it out with a dry section of the cloth.
- If residue is stubborn, lightly re-spray the cloth and wipe again.
Once the included cloth becomes worn or dirty, SurLuster recommends switching to a SurLuster Microfiber Cloth to keep results consistent.
Tips for Best Results
- Avoid using Purify Time in direct sunlight or when the watch is hot to the touch — this can cause uneven application.
- Don’t use it in windy or dusty conditions, and never use a cloth that’s been dropped on the ground — trapped grit can cause fine scratches instead of preventing them.
- If you have sensitive skin or plan to use it frequently, wearing gloves is a reasonable precaution, since prolonged skin contact can cause irritation in sensitive individuals.
- Wash your hands after use.
- This is a topical care product only — not for inhalation or ingestion.
Purify Time vs. Regular Watch Cleaning Cloths
A plain microfiber cloth or jewelry cloth will remove surface dust and fingerprints, but it doesn’t leave any lasting protection behind — the watch is just as exposed to fingerprints and static-attracted dust the moment you set it down again.
Purify Time does both jobs in one pass: it cleans and coats, using the same glass-based coating principle that protects car paint from environmental grime — just scaled down for a watch case instead of a body panel. The tradeoff is that it’s material-specific (metal, ceramic, glass — not fabric or leather), so it’s a targeted tool rather than an all-purpose wipe.
FAQ
Can I use Purify Time on a leather watch strap?
No. Purify Time is designed for non-absorbent materials only. Using it on leather or fabric straps can cause staining, since these materials soak up liquid rather than repelling it. Clean the case and bracelet only, and keep the strap separate.
How often should I use it?
There’s no strict schedule — it depends on wear. A light wipe every couple of weeks for a daily-wear watch is reasonable, or whenever the surface starts looking dull rather than freshly polished.
Does Purify Time remove scratches?
No — it’s a cleaner and light protective coating, not a polish or scratch-removal compound. It can help make fine surface scratches less visible over time and reduce the likelihood of new light scratching by adding a protective film, but it won’t correct existing deeper scratches.
Is Purify Time related to SurLuster’s car care products?
Yes — it uses the same glass-based hybrid coating technology found in SurLuster’s automotive coating line, adapted for watch materials. It’s built by a car care brand, for a very different surface.
What’s included in the box?
A 30mL spray bottle and a dedicated application cloth.
