其實分解嘅主因係乜,有無方法減慢或延遲老化?

其實舊G啲膠咁多年,老化係自然現象。不過我覺得濕氣會令啲膠更易變弱,所以就更易爛。所以G shock 最好放喺乾爽地方保存。如果純粹儲,未戴過就盡量唔好戴。就算要戴,戴完我會先用濕布抹走啲汗,再用乾布抹,然後吹乾先放返入櫃。另外,我會放啲防潮珠,咁會好啲啲。

以上純粹個人意見,希望幫到大家。

網上找到的解說。

Casio G-Shock watches use polyurethane resin. Polyurethane resin is a cross-linked polymer, which depends on the reaction (crosslinking) of isocyanate groups to bond together polyols. The bulk properties of the material depends on the types of crosslinking as well as the type of polyols involved. Strength
The potential lifetime of polyurethane is indefinite, however, like any other crosslinked polymer, it has several common weaknesses. These weaknesses all revolve around depolymerization.
Ultraviolet degradation aka photodegradation: UV radiation attacks polymer crosslinking through a variety of means, both photochemical and oxidative. Regardless of the methodology, UV destroys the chemical crosslinking that gives PUR its useful physical properties - causing both cosmetic damage (yellowing) and reduction in tensile strength (weakness) and elasticity (brittleness)
Hydrolysis: PUR is susceptible to hydrolysis, which is basically another attack on its crosslinked structure through the use of acids or bases in conjunction with water. The water will react with the organic structure of the polymer to combine water broken down into hydrogen or hydroxides with existing structures in the material causing those structures (bonds) to break - hence "hydrolysis".
Ozone attack: Ozone is present everywhere but can be present in higher amounts in certain situations. This is another chemical attack where ozone reacts in a process called ozonolysis to break polymer bonds.
Ketone attack: Ketones and other solvents will have little effect on crosslinked polymers, except for swelling.
Silicone oil and other things will not protect any of the major failure modes of PUR. What will protect PUR against degradation is to keep it out of sunlight and prevent exposure to acidic and basic solutions, especially at elevated temperatures. Also, storing in a vacuum helps.
You also cannot remove the yellow color cast from degraded clear polyurethane.
I'm sure organic chemists can fill in the details.

好多膠十年就已經自然分解,加埋汗水,太陽,氧化,衝擊。。。

橡膠ORING,一年已經開始變硬,三年直情硬哂,十年更加唔使講。

所以膠表每日戴,戴十年無爛已經好好彩。
鋼表就耐用好多倍。
