The OTOMATIC is a thing that bring to a whole new level the concept of anti-aircraft cannon. the mighty OTOMATIC can only be the ultimate SPAA of the game. Instead, just like on the Tank Louis Cartier, you will see a solid stainless steel case back which comes in handy if you are looking to engrave an inscription or gift message on it.You want the ultimate SPAA? the italian have it. However, on the Cartier Tank Solo Automatic, you won't find a transparent case back. It's actually one of the reasons many people start collecting watches in the first place. They can often look through the transparent case back on many watches and marvel at the mechanics all moving together. Many watch lovers prefer a mechanically powered-watch such as an automatic/self-winding watch since it has fascinating micro-mechanics that provide an esoteric value to the watch. These are the big differences in terms of the internal organs of the watches and as you can see they are quite different on the inside.

An automatic timepiece (also called a self-winding watch) is wound up when first used, usually via the winding crown, and then is 'recharged' via a rotor using your movement as you wear it.

AUTOMATIC MOVEMENTДЄn automatic movement, on the other hand, is purely mechanical and is powered by the tension of a tightly wound spring. Quartz is a high-frequency crystal and it resonates at 32,768 revolutions per second giving higher accuracy. The battery sends an electric current to the quartz crystal which then creates a vibration or as watchmakers call it an oscillation. Top Differences Between These Two Types Of Movements QUARTZ MOVEMENTДЄ quartz watch uses a quartz movement which is powered by a watch battery and a quartz crystal. One is an automatic mechanical watch that has a mechanical movement and the other is a quartz watch and has a battery-powered movement. Remember: Despite these slight differences in appearance, these are two very different watches.

Crown: One of the similarities that you will find on the Tank Solo wristwatches are the crowns with their blue cabochon.

Case Material: Models are available in an 18kt yellow or rose gold case (like on the Tank Louis design but for a substantially lower price) and a stainless steel case as depicted here.

Hands: Both the Cartier quartz and automatic Tank Solos have blued sword-shaped hour and minute hands.

Date Window: The date aperture is non-existent on the quartz version but is available in the automatic/self-winding version.

The quartz model, on the other hand, has Roman numerals including the numeral at the 6 o'clock position with the words 'Swiss Made' printed in black beneath it.

Numerals: The Roman numerals for 6 o'clock is missing on the Tank Solo Automatic.

The Cartier Tank Solo Automatic has the words 'Cartier' printed in black on the silver dial just below the 12 o'clock position and 'Swiss Made' printed below the 6 o'clock position beneath the date function.

Dial: The dials on both versions are scaled proportionately.

Seconds & Minutes Track: You will see a railroad-style minute track printed in black on both the Tank Solo automatic and Quartz.

Strap/Bracelet: There are several strap options: You can find the Tank Solo on a black calfskin strap, a black or brown alligator leather strap, and a stainless steel bracelet.

Date Window: The Cartier Tank Solo Automatic has a date window at the 6 o'clock position which is not available on the Quartz.

The Tank Solo Automatic is only available in a larger size 31mm x 40.85mm.

Case Size: The quartz models are available in two sizes, a ladies 24.4mm x 31mm, and a midsize watch which is 27mm x 34.8mm.

Differences & Similarities Between The Cartier Tank Solo Quartz & Automatic As for the inside of the watch, the difference is in the caliber which is the watch's movement, its power source. Although, to be frank, that still is still not all that water-resistant. They both are made of the same material and have a water resistance of 30m/100ft, which is about 30% more than the Tank Louis Cartier. In terms of additional functions, only the Automatic Tank watch has a date window at the 6 o'clock position. They both have the exact same classic look only with a difference in the case size, and a few other differences. Firstly, the overall look of each of these watches is nearly identical. Let's start with what makes these two watches similar before getting into what makes each of these watches different from one another.
