Watch Movements Types : Quartz and Automatic

At the heart of every watch there is a movement. The movement, or caliber, is an essential component in all watches and can’t work without. Its the on responsible for moving the hands and other functions such as calendar, dual time zone and chronograph. To keep an accurate time, a movement should be well made and therefore of a high quality.
When it’s a matter of quality, watchmakers produce different types of  movements to fit different budgets and tastes. While watch manufactures are many, movement could be categorized in only two types : quartz and mechanical.

What’s the Differencewatch-movement-loop

You probably already know the difference without knowing the name of each one. The watch that its second hand has the tick-tick motion which jumps from a second to another is the quartz movement watch. The watch with the smooth sweeping second hand motion, which the majority likes, is the mechanical one.
There are other differences between the quartz and mechanical movement mother than the appearant features and which I will talk about next.

The Quartz Movement

This on is the widespread one and which is cheaper than the mechanical movement. Despit the fact that Quartz movements haven’t so much moving parts, they are very accurate and don’t necessitate a lot of maintenance except replacing the battery. When a watch fan is to choose between a Quartz movement watch and a mechanical one, the Quartz one has less chance because of the lack of technical details and engineering which appeals to them most. Swiss watch brands have set strict quality standards when it comes to Quartz movement manufacturing; Patek Philippe is one of these Swiss brands which designs their watches to abide by these standards. A battery is necessary for a quartz movement to work. A battery sends an electrical current to electrify the quartz crystal to keep the movement oscillating in order to move the watch hands. Quartz movements are found today in popular watches like Nixon watches and which is a Miyota movement.

The Mechanical Movement

Because of their high quality and craftmanship, mechanical movements are the most used to create luxury watches. This type of movements is famous for having complicated small pieces working together to power the watch, which is another feature that requires expertise in watchmaking. Today, technology has allowed mechanical movements to be built with more precision and detail improvement, but the general design hasn’t known much evolution. In addition to the high engineering of a mechanical movement, the manner by this type of movements works is another plus. A mechanical movement utilizes energy from a wound spring to move the watch hands, meaning no need for a battery.

Invicta Speedway 9211

Invicta Speedway 9211

Invicta has been producing really interesting watches with features which appeals to anyone with small budget. Among the most popular Invicta watches, and most attractive designed ones, is the Invicta Speedway 9211. This review will focus on the features of this classy looking silver-tone watch, so bear with me.

9211’s Design

Every watch connoisseur knows very that Invicta copies, or make homages if you want, of major luxurious watches. This one is undoubtly the copie of the “Rolex Daytona” so it’s not only a matter of resemblance. The only thing I noticed in term of design difference is the sunburst which is on the the Invicta Speedway’s dial.

The Caseinvicta-speedway-men_s-watch-9211_5

The case looks elegant and feels solid, not suprising as its a premium design…The case measures 40mm in diamter, not including the crown. It’s made of stainless steel. Like almost all Invicta watches, on the case back you find engraved the model’s name “INVICTA 9211” with of course the logo centered as well as infos about material and water resistance rate.
The bezel is a uniderectional one like on the Pro Diver and which you can make use of to count elapsed time. Unlike the familiar look of Invicta timepieces, the typefont used in numeral on the bezel are tiny and exceeds the 45 and 55 indicators. This adds a feel of precision to the overall look.

The Bracelet

The band of the Speedway is also made of the same stainless steel with silver-tone which matches very well the case and bezel and strenghthen the professional feel of the watch. Invicta has made a nice combination of brushed and polished stainless steel in this bracelet. It also has a double locking diver buckle and is adjustable.

Speedway’s Functionalities

This is the ground on which Invicta is famous when it comes to small budget watches. This watch has three subdials designed to count elapsed time with intervals of 1/60 of a second and up to 30 minutes. The subdial positioned at 6 o’clock is just like another second hand, the dial at 9 o’clock can be used to determine the amount of elapsed minutes and the subdial at 3 o’clock looks like a date window, which is what I thought at the first sight, displays the hour in standard mode which distinguishes AM from PM.

Verdict

For anyone seeking a watch that has an elegant look, the 9211 is definitly a good one. The quality and features are not strong point of this watch, but the price on the other hand is not high either which makes it an attractive piece of fashion.

Wood Types Used in Wooden Watches

If you ever wanted to know from which types of wood are made wooden watches then this is for you.

wood and watches

Acacia

Many people confuse Acacia wood with Koa because of the close appearance of both woods, and which is the rich bronze tone. Like many wood types, Acacia could also be found on other colors than bronze such as tan, red and gold depending on the tree´s origin. To differentiate an Acacia from koa, you only have to pay attention to the grain pattern which resembles ribbon streaks of color. The sources from which originally Acacia is are Tanzania, Africa, & Southern Asia. When it comes to sustainability, Acacia is not a Threatened Species according to IUCN and is not listed in the CITES Appendices, but at the contrary in some areas is considered invasive.

Koa

Koa is one of the popular wood types and is one of the most attractive ones when it comes to native hardwoods. Hawaii is known to be the origin of this type of trees. Koa has also another interesting feature for industrial ends as it’s a wood that render very nice and finishes smooth with a beautiful soft looking surface. Just like Mahogany, Koa wood is able to produce a great amount that range from medium to reddish brown depending on the harvest season. The grain pattern of Koa is moderately intermeshed, and sometimes wavy. Just like Acacia, Koa is not listed in the CITES Appendices.

Bamboo

Also known as Bambusa genera, Bamboo is another popular wood type, and which makes think of Panda. Bamboo has an attractive soft surface as well as a very unique shape and texture. This made of it a decoration used in many cartoons. Bamboo has an amazing capacity of growing up to 100 feet. South Asia is famous for being utlimate source of Bamboo and is not on the IUCN Red List of Threatened Species.
In wooden watches manufacturing, one way of using Bamboo is gluing sanded strips together and finishing them to become a bamboo board before turning them into watch cases and strap links. This method is used by Jord which is well known for making wood watches.

Ebony

This one is the most easy to guess its origins. Ebony, also having the name of Diospyros ebenum, is founded in     East Africa, precisely Mozambique. This type of wood has an intrinsic feature of having a glossy sheen and it has a high color saturation. Even though the texture of Ebony is uniform and fine, the straight grain is hardly made out because of the tone depth. To make complexe shapes, such as watches and glasses cases, ebony is challenging to exploit and woodworkers must regularly check their tools and make them sharp to reduce pulling and poor edging due to the hardness of this wood type.
