Momentum SmokeJumper 44MM Watch Black with Luminous Dial & Black Bramante Leather Strap


The Momentum SmokeJumper 44mm Watch features a vintage inspired dial, domed crystal, a day/date, sapphire crystal, and a stylish black-ion coating. Momentum Watches are excellent for any bushcraft, outdoor, sports, water activities and all rugged adventures one might enjoy because these wrist watches are waterproof, scratch-resistant, durable and tough. All our Momentum Watches feature the Sapphire Crystal Watch Face which ensures your watch will handle all the knocks and punches you might throw at it.

Momentum have manufactured custom-dial watches for fire-fighting crews and with this the SmokeJumper was born by the request of several “Smokejumpers” who had requested a light watch in a more retro, vintage style. This watch is engineered in space-age, solid titanium which is what makes this sports watch so slim and light that it’s easy to forget it is on your wrist.

The Momentum SmokeJumper in its 44mm case has a durable black-ion finish for a “stealth” look, complemented by a subtle red tip on the second hand and 24-hour military time scale around the inside of the dial. This dive watch comes with a scratch-proof sapphire crystal which is standard on all SmokeJumper models. Sapphire Crystal is so resistant to scratches a hard knock will not scratch the glass. Featuring a locking, screw-down crown ensures rock-solid waterproof performance and the titanium case is naturally non-allergenic. The Momentum® Smokejumper Watch is a great combination of modern watchmaking technology and vintage style, perfect for anyone who loves a mix of modern and vintage with a rugged performance.

Scratch-Resistant Sapphire Crystal


What is Sapphire Glass?

Synthetic sapphire combined of crystallised aluminium oxide

Astonishingly Sturdy
Value of 9 Mohs of mineral hardness same as titanium carbide

Scratch Resistant 
Superior to Quartz or gorilla glass

Synthetic Sapphire: 
A synthetic sapphire crystal or “glass” is actually not glass at all. It is a very hard, transparent material made of crystallizing pure aluminum oxide at very high temperatures. Synthetic sapphire has the same hardness as natural sapphire gemstones, but without the colouring agents that give the gems their various hues. When it is heated, the synthetic sapphire forms round masses, that are then sliced into pieces with diamond-coated saws. These disks are then ground and polished into watch crystals. (One reason sapphire crystals are relatively expensive is that the tools required to cut and polish this extremely hard material are very costly.) Sapphire (whether natural or synthetic) is one of the hardest substances on earth. It measures 9 on the Mohs scale, which is a system for rating the relative hardness of various materials. (Diamond measures 10, the highest rating.) Watch crystals made of synthetic sapphire are often marketed as “scratch resistant” or “virtually scratchproof” because they are very difficult - but not impossible - to scratch. Diamond can scratch them; so can man-made materials that incorporate silicon carbide, which, with a Mohs rating of between 9 and 10, is harder than sapphire. So, if you accidentally scratch your watch on a simulated-stone surface or a wall that incorporates some of these silicon carbide materials, it could scratch the crystal.

AR Coatings:
Sapphire crystal is more reflective than mineral crystal due to its higher index of refraction. (1,8 compared to 1,47). Applying one or more layers of AR (anti-reflective) coating will limit this reflection to a very low level. Very often, lines and marks on the top surface of a sapphire crystal are mistaken for scratches but are actually the scratched AR coating, or just AR coating wearing off after time. An AR coating on the inside of the crystal provides a good AR performance while avoiding this problem. If you do scratch a sapphire crystal, then it cannot be polished away and will need to be replaced.
 
Waterproof gasket:
As both mineral and sapphire crystals are extremely hard, they have little or no “flex”. This means that when the crystal is inserted into a hard, steel or titanium watch case, it requires a gasket to ensure a waterproof seal.  These crystal gaskets are typically made of nylon, and are either flat, “I”-shaped or “L”-shaped. (see example above). The crystal is pressed into the case, using a crystal press tool. When it is pressed in, the nylon crystal gasket is “squeezed” between the crystal and the case rim, making a reliable waterproof seal. Over time, these crystal gaskets can become brittle and break, so it is a good idea to change the crystal gaskets every few years, to ensure the ongoing waterproof performance of your watch.
