How to oil a watch movement?

　　If the watch is not running smoothly, we need to lubricate our watch in good time. So how exactly should the movement be oiled? Let us take a look below.

　　Steps for Oiling a Watch Movement

　　According to the operational requirements of the movement, the parts that can be oiled, the type of oil to use, and the quantity of oil are introduced as follows: clock oil can be injected between the mainspring coils using three drops from an oiler pen. The pallet pin, pallet jewels, and pallet arm slots must not be oiled. Oiling the balance spring is strictly prohibited. Because as soon as the balance spring has oil, it will produce a sticking effect.

　　The pallet pin, pallet jewels, and pallet arm slots must not be oiled. Because the pivot angle of the pallet fork is small, and the distance between the pallet fork pivot and the shoulder is too close, any oil applied will flow onto the fork body. Due to the viscosity of the oil, this will instead increase the running resistance of the pallet fork, making it sluggish and reducing the impulse transmission.

　　Oiling the balance spring is strictly prohibited. Because once the balance spring has oil, it will cause a sticking effect, affecting the amplitude of rotation and vibration frequency of the balance wheel. Silicone grease should be applied to the stem crown, but not in excessive amounts; lubricating oil is strictly prohibited to prevent the waterproof gasket of the stem crown from deteriorating. All the above are taught by professionals, and if there are any discrepancies, your guidance and comments are welcome.

　　Clock oil can be injected between the mainspring coils using three drops from an oiler pen. Clock oil can also be applied to the setting lever pivot of the keyless works, setting wheel pivot, ratchet wheel bushing, idler wheel pivot, and between the clutch wheel teeth and winding pinion teeth. For example, on Rolex watches, two drops can be injected into various parts using an oiler pen. Watch oil should be applied to the barrel arbor and mainspring barrel, barrel arbor and upper/lower bridges, upper and lower pivots of the centre wheel, intermediate wheel, second wheel, upper and lower jewel holes of the escape wheel, small center pivot of the centre wheel, impulse faces of the pallet stones, and upper and lower jewel holes of the balance staff, which can be applied using a fine oiler with a single drop.

　　Steps for cleaning leather watch straps

　　1, when a leather strap develops an odour, dip a toothbrush into a little soapy water, quickly scrub the dirty areas, and then wipe clean with a slightly damp cloth.

　　2, spray medicinal alcohol with a concentration of 99% onto the leather strap, then apply a coat of beeswax; the odour of the leather strap can be instantly eliminated. After three applications, this can be permanently removed, providing exceptionally strong disinfection, moisture-proof, and mildew-resistant benefits without harming the leather strap.

　　3, you can add a little table vinegar to warm water, soak the leather strap for 2 hour, and then wash with soap; the odour of the leather strap will be reduced.

　　4, you can also pour floral water onto a towel and then use the towel to wipe the leather strap; the leather odour will disappear, and the watch leather strap will be thoroughly cleaned.

　　5, detach the strap for cleaning. Use a suitable amount of washing liquid as the cleaning solution, soak the strap in warm water for 10 minutes first, and then scrub the crevices of the strap using the softest toothbrush.

　　6, professional cleaning equipment uses an ultrasonic cleaning machine (note that the bracelet should be detached for cleaning to avoid vibration damaging internal parts).

　　7, to avoid soapy water seeping into the leather during cleaning, the entire process should ideally be completed within 20 seconds. In addition, consumers can also apply some leather oil to the leather strap. Leather oil has a protective effect on the strap, making the maintenance work more thorough.
