sinn watch getting rusty?

[gavinang83]

Hi guys,

i have a sinn 857 and i noticed some rust on the bracelet and watch case..is this normal? i thought stainless steel doesnt rust..anyone encountered this before?

[feilong108]

Rusty????i suppose it is dirt i suppose...have not hear of S.S case or bracelet get rusty....so far my lao ko ko datejust doing well despite of grand old age of 22yrs...

[gavinang83]

i dun think it is dirt, cos it doesnt come off easily

[feilong108]

if the watch is under warr i presume it will be the best to revert back to the respective service centre to check the problem....

erm...look like dirt to me...can try to use a toothbrush to scrub gently under running water

Have you ever in contact with sea water? BTW, if do, good luck if you didn't wash it over fresh water.

I got a Tag Heuer that is past over 20yrs yet don't have this "rust" even with me for diving cos I wash it over tap water each time back from "outing".

[gavinang83]

nope no sea water..just the occasional rain water which i never wash off with tap water..anyway i did try to brush it off just now using toothbrush under tap water..it did remove most of it but it left some marks..something like metal being 'eaten' away

[feilong108]

well...it is great to hear that the simple method helps!!! Btw do go to the service centre to double -check....to play safe...i feel that Sinn watches ought to be real tough as it is made of submarine steel right????

I don't know how tough they're supposed to be but how many rusty submarines have we seen?

Well please don't be mistaken that submarines steel won't rust. Haha..anything that is into contact with sea water, over period of time would definitely rust.

That is why we have shipyard doing maintenance work after period of time out at sea. BTW, submarines by Sinn only claim to withstand pressures but no info that it is able to absorb or withstand rusting.

This is an interesting development and I hope TS will update. Tx.

Stainless Steel Corrosion and Prevention...

Stainless steel is known for its ability to be a clean shiny surface that better resists corrosion and rust than non-treated steel due to addition of mostly chromium, molybdenum, nickel, niobium, and a lower carbon content. Tegimentation just makes the upper surface harder to sustain scratches, dings and dents from accidental knocks. Thus dirt, dust and grime can still put stainless steel at risk for corrosion and rust. This residue can form up from the evaporation of sweat which has harsh corrosives such as salt (sodium), acids, akalis and proteins which deposit on the surface especially in hard-to-reach areas between lugs and bracelet links. What makes it worse is that after evaporation, the corrosive elements become more concentrated and rapidly attack the surface leaving holes or "pits" (aka pitting). Fortunately, stainless steel responds well to cleaning, never wearing out from excessive cleaning, as long as certain rules are followed :

1. Water and a cloth.
Routine cleaning can be accomplished by using warm water and a cloth. The water at least dilutes if not removes the corrosive salts, acids and alkalis. This is the least risky option for cleaning stainless steel. Dry with a towel or cloth to prevent water spots. Wipe in the directions of the polish lines.

2. Mild detergent, (dish washing liquid) and cloth.
For cleaning that needs more power, mild detergent and warm water can do a great job without damaging the stainless steel. Make sure you rinse the surface thoroughly to prevent staining and spotting. Towel dry to prevent water spots which can be caused by minerals in water.

3. Glass cleaner for fingerprints.
Fingerprints are one of the biggest complaints about stainless steel, but can be taken care by using glass cleaner or household ammonia. Rinse thoroughly and towel dry. There are some newer types of finishes for stainless steel that resist fingerprints, a must if your pint-sized helpers leave their mark on your stainless steel appliances.

4. Stainless Steel Cleaner.
If you’ve had staining or scratching, or need to polish your stainless steel, a stainless steel cleaner may be a good option. Some of these cleaners and polishes can help minimize scratching and remove stains. They also can polish stainless steel surfaces nicely. Read the directions on the stainless steel cleaner and test in an inconspicuous spot. Be sure to rinse thoroughly and towel dry.

At the end of the day, care matters, for even good old gold is not protected against corrosion from sulphur, chloroauric acid (aqua regia) and of course mercury.

wow...learn so many new things in this thread regarding rust and metals...great to learn from the knowledgeable people here...it sure beats going thru Google..

Yes, a good effort to share. Tx.
