Difference of all of the Rolex watches?

[Topic]

What is the difference and the meaning behind all of the models???

1.Datejust - i'm guessing its an ordinary watch, just to tell the time or date on correct?

2.Daydate - same thing just adds the day

3.Turn-O-Graph - no clue what it means or what its used for haha...help

4. Perpetual - same thing as daydate/datejust but without the date and day?

5. Air King - I guess same as perpetual...no date and no day

6. Explorer - Just tells you the time in another part of the world?

7. GMT-MasterII - same as explore only different looking?

8. Daytona - Has a timer for racing etc.?

9. Milgauss - What da??? I have no clue what its used for.

10. Sea-dweller - Sumbariner with more depth?

11. Yacht master - no clue

12. Submariner - used for diving and the bezel tells you how much air your tank has left?

Generally correct, Milgrauss designed for people working in areas that may have a higher than normal magnetic field.
Would not call the Datejust "an ordinary watch"

Explorer has fixed bezel so that Cave explorers could tell if it was AM or PM via the 24hr bezel.

GMT - has the ability via the bezel to keep tabs on a second time zone

Yacht Master - Does what it says on the tin

SD has a HEV for Saturation dives

Thanks for the response, i own the DJ and i use it for the ordinary use thats what i mean by ordinary. Also what are saturated dives? and what is a HEV for i know it stands for helium release valve?

As for me, the most useful watch is the GMT II, with the different timezone. Secondly, the Daytona is useful with the chrono functionality. Everything else is just for the look and time. Most of the time, I used my cellphone for time and date :) ~Hien

Perpetual, for Rolex, means an automatic. All of the self winding models are "Perpetuals", and generally they are "Oysters" too.

Oyster is the Rolex designation for their waterproof case.

Air King is a dial name carried over from the early fighter pilots who wore Rolexes for flight calculations and affectionately called their watches Air-kings. Having a reliable time-piece for calculating position, fuel remaining, and ground speed meant life or death.. Pilots were wearing wristwatches long before they became common for the average man..

Daytona was a name Rolex coined for their Chronograph to make it sound more racing oriented. The Omega Speedmaster was the preferred timer for racers in the late 50's and 60's, and Rolex wanted to be more competetive.

GMT was coined from Greenwich Mean Time, the standard time-zone reference for navigators and pilots....This watch has the ability to show GMT time and your local time as well.

Exploer II was initially conceived to be able to tell night from day using the 24 hr bezel (yes, specifically for cave exlorers). The new movement allows it to be used for separate timezones as well.

What is the difference and the meaning behind all of the models???

1.Datejust: Just the date, and time.

2.Daydate: Day and Date. DD's don't come in steel.

3.Turn-O-Graph: DJ with bi-directional bezel. Can be used for timing things.

4. Perpetual: Just the time, smaller than DJ

5. Air King: Like the Perpetual.

6. Explorer: Strictly spoken like a bigger AK, black dial only. Comes in steel only. But the Explorer II is like the GMT II, but has a fixed bezel.

7. GMT-Master II: Like the Explorer II, both bi-directional bezel. Gives you a third time zone.

8. Daytona: a chronograph ("stopwatch"), and also a tachymetre (timing speed).

9. Milgauss: Just the time, but watch is as big as the sport's Rolex (40 MM), plus highly anti-magnetic (1,000 Gauss).

10. Sea-dweller: comes in steel only, is WR to 1,220 M due to a Helium valve, thicker crystal and caseback than the Sub Date. Date function but no cyclops.

11. Yacht master: just the date and time. Like a "dress Sub". Comes with a Platinum dial. Always red second's hand and red YM writing.

12. Submariner: comes either with a date or no date. The no date comes in steel only. WR to 300 metres. Bezel, uni-directional used for timing dives or other events.

Very well described everyone.

Ill just add....

13. Cellini - Usually time only with no date feature, comes in quartz movement, automatic movement, or manual winding movement. Usually available in gold or platinum and functions primarily as a dress watch. Not recommended for water related activities.

thanks guys i learned alot...What does quartz movement mean also?

Quartz movements are watch movements that are powered completely by some kind of battery source. They usually feature a second hand that "ticks" in complete one second intervals rather than sweep smoothly around the dial like an automatic movement. They do not get power from wrist movement or hand winding.

Quartz watches are also generally more accurate than automatic watches as they can be up to 99.99999% accurate to atomic time. Radio controlled quartz watches can be up to 100% accurate supposedly but I always considered that inconclusive. Quartz movements were introduced sometime during the 1960's and have become widely available and more common than automatic movements today.

Speaking of quartz watches, Rolex also made the OysterQuartz (no more made). It was special in as much as it, like the Milgauss, was highly anti-magnetic (to 1,000 Oersted). It also had a special Oyster case (more squarish to the look) and an intregrated bracelet, specially designed for the OQ.

so why does Rolex use automatic instead of quartz since its more effective?

[SPACE-DWELLER]

Question is if quartz is "more effective"?

Well regulated, an automatic Rolex can beat the precision of a quartz watch.

The fast-beat (28,800 bpH movts.) "killed" the quartz you might say, after a period where the automatics were not as popular as today, due to the quartz' initial popularity.

And an automatic watch has what you could call "soul". Luckily, the mechanical (includeds manuals and automatics) have a renaissance after a period where the quartz was seemingly making the mechanical movements obsolete.

Well automatic movements are considered to be more appreciated by many because of the very fine craftsmanship and workmanship that goes into making an automatic movement. They are definitely much more complex and require very careful construction when building them. They are also generally more expensive than quartz.

People prefer automatic movements because they like the smooth sweeping hand but also because of the build quality of them. Rolex has been using them since the year 1931 because automatic movements have always been a great tradition in watchmaking and has been a part of the long history of watches.

Many agree that automatic movements were first discovered in the 1770's by a watchmaker named Abraham-Louis Perrelet. He discovered the world's first self-winding (automatic) movement in a pocket watch. So automatic watches have always been a long tradition in fine watchmaking and Rolex has long followed that tradition by making automatic watches.

I also agree with what Bo has said. A well regulated Rolex can definitely beat the precision of a quartz. So "effective" may not be right term to use since automatic movements are very effective and durable. However I would consider quartz to be somewhat more "precise" in general.

Just make it simple.

DateJust is a cheaper version of Day-Date with out a Day function. When remove the date function then you have left to Air King etc..

Now, 40mm sport model, you have Daytona and the rest.

And the rest are:

GMT Master II and Explore II. Both are the same except Explore II has stuck bezel.
After reduce 24 Hr hand then you have left Sub date, SD and Yatch Master. Sub and SD are same except one has higher depth rating. Yatch Master is higher end of the three because it come with solid precious metal like platium bezel and the othe come with steel bezel with aluminium insert. Just like car, with solid alloy wheel and the other come with stell wheel with hub cap.
Then you remove date function then you have left only Sub no date or Milgauss.

Quartz watches are only accurate if the quartz stone is cut properly. My Rolex Oyster Perpetual, and IWC and Omega Dress Watches, all either automatic or manual wind, keep better time than most cheap quartz watches I've owned.

True, there is the possibility that mechanical watches can be more accurate than quartz, I am not ruling that at all. In fact, I like it when automatic watches are more accurate.

However, I've owned my Wenger watch, which has a quartz movment, for over 10 years. Generally, its more accurate than all my automatics as it only deviates by about a minute each year. However, with the new blu hairspring on the GMT and Daytona, it seems that those movements can blow my Wenger away in terms of accuracy.

"Just" to add a bit to the "Datejust" discussion...

"Date" because the watch has the "date" complication, "just" because the date flips over "just" as midnight passes. "Just in time" = "Datejust". This was a big deal when it was introduced in the 1940s.
