New Old Stock Omega 300 165.024 dial

I have been looking for a New Old Stock Omega 300 165.024 dial to replace my Omega 300 for a while and I have finally managed to find one recently. Since I have one Omega 300 in vintage dial condition, it will be nice to have one in NOS condition..

Vintage Omega Constellations watch

During the 1950-60s, the brand positioning of Omega was the same as Rolex. In fact, some of the Omega watches from the 1960s were higher than the Rolexes of that era. For the past years, I have not seriously focus on collecting Omega watches till recently where I have put in efforts to focus on Omega watches in precious metals, Constellations series if possible and in good conditions. 

These are my small vintage Omega collection

Omega 168010/11 white gold Constellation with diamond indexes Cal 564 (1966)

Omega 168010/11 white gold Constellation with diamond indexes, 24 jewels Cal 564 from the year 1966. This is a deluxe version of case 168.010 with triple diamonds on three of the quarter hours and one diamond neatly integrated into the date quarter hour. 

I have been a look out for white gold Constellation. Previously, I have found a white gold Omega Constellation and but I have decided to return it owing to the redial. This time, I am fortunate to find another white gold constellation. I have to trade away a Rolex automatic date plus cash top up for this Omega with "hidden crown". The case size is only slightly larger than the traditional Connie at 35mm but with the lug width at 19mm and a smaller bezel, it has given the perception of  a larger dial area on display and the watch will appear larger on the wrist.

I am slowly growing and tightening my Vintage Omega collection focusing on precious metal like the solid Pink, white gold series, and Constellation series if possible or else the focus of collection will be very wide. The only exception is the Omega Seamaster 300 and some with rare Middle East dials (the the watch made for Kim Il Sung)  where the watches are in stainless steel

Rolex ref 6144 (from 1952) Royal

This is a Rolex Royal ref 6144 with subsidiaries seconds hands. It has a nice protruding Rolex Crown and 2,4,8,10 numerals on the dial. The watch is from the year 1952. I was not expecting to get any watch today from Mr. Wong but this beauty is too good to miss as not everyday can we find Rolex with subsidiary seconds hand.

The Rolex Oyster Royal is a stainless steel Rolex series made in the 1950s and 1960s. It used at least two different mechanisms, the 700 and the 710. The 700 models use a sub-second hand and the 710 models use a center-second hand.

Mechanism: 

The 700 series represents the fourth iteration of the Aegler Hunter 10 1/2 movement made for Rolex. This final version used the same simplified balance wheel as its predecessor the 'Superbalance Precision' but only used 15 jewels. The mechanisms are usually stamped with 'Rolex 15 Jewels Swiss Made' as well as 'Rolex Patent 10 1/2" H'.

The 710 is closely related to the Aegler 700. The primary difference is the position of the second hand. The 700 is "sub second", whereas the 710 is "center second".

Rolex Prince jump hour versus Gruen Doctor’s watch

The Rolex jumping hours complication in an art deco–inspired stepped rectangular case does not exactly scream Rolex, but that is exactly the charm of the Railway Prince (ref. 1571).Rolex Prince jump hour versus Gruen Doctor’s watch.

Besides Rolex, Alpina Gruen and Gruen have also produced the Jump Hour Doctors' watches

Omega Seamaster 300 & its Variations

There are several broad variations for the Omega Seamaster 300 from the 1960s. One is the 165.024 no date version and the 166.024 date version. Another important one is the Big Triangular with fixed lugs made for the military use.

For the Omega civilian versions, there were some differences in the Omega Seamaster 300 165.024 as well namely:

1. Cases were made by Huguenin Freres (HF) and Centrale Boites (CB

2 Baton hands versus Sword hands

3. Naiad non screw down crown versus deep screw down crown.

4. Big triangle vs small on dial. The Big triangle version commands a premium over the smaller one as it was earlier and much rarer.

5. Movement ; There are two movements for the Non date version (Cal 550 for the US market, and the 552 for the European markets and Asia. For the Date version, the movement should be Caliber 565. There are two dates colours namely white and Black.

6. Watchco version : This is a version NOT original factory manufactured or assembled but being assembled using Omega Original parts for the Omega Seamaster 300 plus using the Movement 550, 552 and other movements from other Omega watches. The prices of these are almost half of the original so collectors will need to be careful in their hunt as most vintage watch collectors will avoid collecting these.

Like any watches that were produced for several years, there were also versions using the cross over parts. For example, there were examples where the hands were the earlier baton hands versus the later swords hands. There are also variations in the bezel's fonts.
