2998

Produced 1959 to 1962

With eight sub-references, this is my favorite reference to accumulate, each with its own little characteristics. These watches are so old, and so easy to change, that it is very hard to say if a piece is original. We have instead to satisfy ourselves that it looks original.

In this reference the dial and bezel are a large proportion of the value. If these are missing then be prepared to adjust the value substantially, bearing in mind the suitable parts may never be found.

Case condition on available watches in the market may never be very good. We have to make allowances, and accept a damaged or polished case, or resign ourselves to the idea of never owning one.

The chrono seconds hand was fitted in three executions, the straight hand, shown in the 2998-1 below, the very, very rare lollipop, and the spear seen in the later references below. At no time was the square ended spear fitted. Omega currently offers a service replacement straight hand, but it has a fatter tail and looks wrong. The lollipop hand has been seen on all examples, but without any way of knowing if it is original or not. One surely has to ask, does it matter? (It will, should we ever discover a way of verifying it – but until then, no).

-1 and -2 should have black BASE1000 bezels. These are extremely rare and very often replaced with a DO90 bezel. Recent sale of BASE1000 (as of September 2018) has been rumored to be $20,000.  I think even a poor one might reach half that, if true.

 

Movement

These are all fitted with the early type of Calibre 321 movement, most easily identified by the symmetrical clutch bridge.

There are some other differences too, but I always use the clutch bridge as confirmation that we have an early movement. We must always be alert to the possibility an old number bridge has been transferred onto a newer movement. This is usually obvious from a  colour difference in the copper plates and bridges.

Symmetrical bridge
Asymmetrical bridge - Not seen on correct 2998

Dials

The 2998-1 and -2 have slightly different dials. The early dials have short indices on the subdials:

Above ist the right subdial showing short indices on the subdials. These are seen on the -1 and -2

Here is a sub dial from a 2998-62 showing the longer indices on the subdial. This length remains the same through to the end of speedmaster production.

There is one more point to check. The “O” in Omega in the very early dials is known as an Oval O.

See here on right:

Above, note the round oval in Omega.
Above, note the flattened oval in Omega.

Now we will look at each sub reference:

2998-1

2998-1 with round Oval dial, short indices. BASE1000 bezel. This example is correct.

Serial Range: 1730 1xxx – 1776 1xxx

2998-2

The above example is in very good condition, but it has a DO90 bezel where it should have the BASE1000. Otherwise it is correct. This is quite commonly seen in 2998 1 and 2’s, where the BASE1000 has been replaced with a DO90.

2998-3

2998-3. Correct. Dial is very attractive, and complete – no decaying of the track. Slight brownish tint that will add to value. Hands are correct, note the chrono is unpainted which I accept, although not certain it is original, I see so many.

Serial Range: 1776 1xxx – 1776 5xxx

Dial

  • Stepped
  • applied metal logo
  • No Professional text

Bezel

  • Black BASE500 bezel with dot over 90 (DO90)

2998-4

2998-4 On sale at Chrono24.

This is a good learning watch. Look at the hands, the hour and minute hands are too short. These come from a Seamaster. The hour subdial has crept all the way around, indicating some adjustment or service required. The bezel is from a much later watch The crown does not look the right size, and the pushers are of different dimensions. This watch underlines how careful you have to be when looking at a watch, even on a well known site like Chron24. I would price it at between poor and fair.

2998-5

2998-5. Owned by a member of Omegaforum.net. This shows beautifully aged plots, correct hand layout and a fine DO90 bezel. It would appear the hour counter is exhibiting chrono creep. While the hands look a little battle worn, they fit the character of the watch. This is a very good example of a correct watch that is highly desirable because of its aging.

2998-5. Offered by Antiquorum November 2021.Triangle lume on the Aplpha hands, and a very nice dial. Correct DO90 bezel. This is a nice example.

Crown

  • 7mm

Bezel

  • Black BASE500 bezel with dot over 90 (DO90)

2998-6

2998-6. Another very good dial. Triangle style hands. It is possible this reference should have the spear chrono hand, while this carries the straight chrono hand of the older variants. It probably had the spear hand originally, but as everything seems to match I am leaving it.

Serial Range:    1894 6xxx *

 * (Edit October 2017 – since writing this site, MWO has produced serial ranges for the last 2998’s as a group. They suggest that 2998-6, -61 -62 can fall into the range 18419xxx to 19834xxx. As they spent time at the Museum with the records, I would suggest readers follow this range when viewing a watch)

2998-61

2998-61. Poor bezel. All correct hands. This is a very nice original watch. the plots are a little patchy but acceptable as the rest of the dial is so nice. This to me is a very attractive watch, worth paying a premium.

2998-62

2998-62. This is actually a watch I built up by me from salvaged parts. It is useful to see this sort of thing as it shows how easy it is to build up these watches and pass them off as original. It has some incorrect parts. The Omega supplied chrono hand – which is too fat in the tail, should be a spear in this reference. The subdial hands should be stick, not leaf. The dial has narrow T SWISS MADE T markings that should be on a 105.003. I used a Seamster 321 movement. It is very interesting illustration of what can be done, and what we should be looking out for as more and more unscrupulous people coble together watches out of parts. This is a great looking watch, but not original. It is because of this watch, that I am now deeply suspicious of any wrong part on a watch. Now, when I see something as innocent as an incorrect chrono hand, I start to examine everything.

Things to watch on all 2998’s

  • Correct bezel – all -1’s and -2’s should have BASE1000 bezels
  • Correct dial for reference. Early dials have short indices on subdials, and NONE ever had T marks, these are often seen incorrectly fitted.
  • Hand length. The alpha hands are often replaced with incorrect length ones. See here
  • Pusher size. These are often replaced with incorrect larger pushers.
  • Chrono and subdial hands, need to be checked for correctness
  • This reference is so valuable that people cobble together watches from multiple sources, often with Seamaster movements and hands.

*Serial ranges quoted here are distilled from experience, and then cross referenced with the MWO book. I simply cannot continue with my own estimates when they have published well reserched data – so I have brought my serials in line with MWO with some rare exceptions when my observations have shown others. Remember with early numbers, it’s all down to observation.

Here is a little cautionary tale:

Below is what Omega did to watches when you sent a beautiful old watch in for service. It may be different now, but I would never send a watch to Bienne for fear they take off all the old parts and replace them with new

2998-3. This is all wrong. This watch got sent to Bienne, Omega’s headquarters for a service, probably in the 1980’s. They replaced everything we consider valuable and as a result this watch is really only worth the value of the case. The dial, hands and bezel are all replaced with service parts.
