    Hello All !

    I learnt so much on this forum i thought it is time I share a bit more, with my little means.
    I would like to present you a watch I recently bought from eBay, very impulsively i have to admit.:whipped:
    I do not seek any approval but please any criticism is more than welcome.

    So here it is : an Omega Speedmaster 105.002 DEPORA

    DSC_0007.JPG


    DSC_0009.JPG

    I will now try to describe the watch and its characteristics, MWO being my main source of knowledge.

    The reference 105.002 is relatively rare as it was produced for a period of about one year.
    According to MWO p.264, 2200 to 2660 watches of this reference were produced.
    This reference is actually a 2996-62 which has been renamed due to the introduction of a new codification by Omega : the Mapics system

    Movement :
    20160922_204452.jpg

    A1 (1st gen.), A2 (Transitional) and A3 (2nd gen.) types of 321 are correct for this reference
    Mine is the A1 type, with a fair amount of corrosion.

    According to MWO, the serial range for this reference is :19.583.xxx to 20.525.xxx
    Speedmaster101 states 19.584.xxx to 19.834xxx and 20.525.xxx
    Mine falls in this range, being 19.584.2xx, which makes it an early one.

    Case:
    The case is of course the A1 symmetrical version, with the straight lugs.
    The presented reference has some pitting type of corrosion:
    Image_20160922_173843426.jpeg

    Dial:
    According to MWO, both type are possible for this reference:
    A5: Tall Markers / Low SWISS MADE
    A6: Tall Markers / High SWISS MADE (later models)
    My reference is the A5 I believe, so for earlier models which is consistent with the serial

    Image_20160922_172319457.jpeg

    This color of this dial has slightly turned brown, which is due to an oxydation process
    Much more precise information about this phenomenon is described following this link:
    http://speedmaster101.com/blog/brown-dials/

    Bezel:
    The bezel is the B1 type, which is the Dot Over 90 aka DON or Dot diagonal 70
    The watch must have received a strong shock at 6h as shown by the picture below:

    coup sur lunette.jpeg Image_20160922_172742296.jpeg

    Hands:
    2 different configurations are possible for this reference.
    B4 Alpha variant 4 is observed for references 2998-6/62 and early 105.002s.
    The presented watch is mounted with the alpha hands.
    Another possibility is the C1 baton drop seconds for latter pieces.

    Image_20160922_172724103.jpeg Image_20160922_172856124.jpeg Image_20160922_173010644.jpeg Image_20160922_173055611.jpeg

    A fair a mount of corrosion can be observed.

    The luminescent material is a mixture between tritium (an isotope of hydrogen) mixed with zinc sulphide.
    Basically, the tritium emits some energy (beta radiation) with is absorbed by the zinc sulphide and then emits visible light. The pigment has now degraded over time as well as the radioactive activity of the tritium which make the material non luminescent.

    Caseback:
    Type A3 Speedmaster in Center with double bevel is correct for this reference
    DSC_0009.JPG Image_20160922_173821975.jpeg

    As you can see, there is a special engraving M046-DEPORA-64

    According to MWO p. 160, the source of this inscription is relatively vague.
    A most shared hypothesis is that DEPORA stands for DEPartment Olah RAga, which relates to the Indonesian Ministry of Sport. Theses personalized models may have been produced for trainer or athletes.
    However this has not been confirmed by Omega.

    This engraving has also been observed with the reference 2998-62, in this nice post:
    https://omegaforums.net/threads/my-ck2998-62.13737/
    The watch presented in the link above is in far better shape and bears number 047, which is just next to mine.

    20160922_204342.jpg

    Crown:

    Two configuration are possible:
    Type A1. 24 - Narrow Omega Feet, which can be observed on mine (diameter 6.75 mm and thickness 3.8mm)
    Type C1 Mercedes (not certain)

    Image_20160922_173700237.jpeg

    Pushers:
    According to MWO, Type 1 Small (diameter 4mm, thickness 2.5mm) is correct for this reference
    Image_20160922_173727935.jpeg
    As you can see, bottom (left) pusher seems taller than top (right) pusher.
    They look indeed identical in shape. Bottom pusher has much more spring than the top one
    Image_20160922_173753003.jpeg

    Glass:
    Category A Hesalite is correct for this reference.
    I am not sure if the presented reference has the narrow (type A1) or the short feet (type A2) Omega logo
    I guess it is closer to A2 than A1 as the feets are really short
    Image_20160922_173257365.jpeg

    Bracelet:
    Bracelet is the correct 7912 with #6 end links
    Following this link you will find a very useful table for the omega speedster bracelet:

    ----------

    The watch is now at my watchmaker's for a revision (movement only)
    I first wanted to switch the dial with this one but I decided to keep the original.

    Congrats for the depora. And as we finally have a number with a "6", my guess is that the ends should read "G4" and not "64".
    Probably delivered to Taiwan like 3 other observed.

    A million thanks!
    All that is a bit your fault as the madness began as soon as MWO was offered to me ! ::psy::;)
    Now that you say it, I think you are right for the G4
