One of the most admired vintage “Omega Speedmaster” models is the historic reference 2998. Omega has released a couple of limited editions of this timepiece along the years and in 2018 they are unveiling the “Omega Speedmaster CK2998 Pulsometer”.

This watch is based on the original CK2998 reference model that was introduced back in 1959, as a second generation “Speedmaster”. It would go on to be in production until 1962, after which it was succeeded by references: 105.002 and 105.003. At EiT we still currently hold in stock the limited edition “Omega Speedmaster Moonwatch Chronograph CK2998” (Ref#: 311. which was released as a commemorative piece based on the original, but with a racing car theme color-scheme; you can check our current listing here and read an in-depth review here.


“Omega Speedmaster Moonwatch Chronograph CK2998” (Ref#: 311.

The 39.7mm case is made of stainless-steel with a mixture of brushed and high-polish finishing. Its solid screw-on case back features an engraving of the iconic Omega “Seahorse” plus the unique number for each of these limited edition pieces.

Lens Position: 2146

Mounted to the case is a fixed black ceramic bezel with a pulsometer scale engraving, instead of the typical tachymeter scale. The pulsometer bezel is a useful tool for the medical staff and allows to measure a person’s heart rate. Often a pulsometer scale can measure in units of 15 heart beats, or sometimes 30 beats, as is the case of the one found on this new “Omega CK2998 Pulsometer”.

It comes equipped with two push-pieces that activate the chronograph functions with a setting-crown in-between them. It has a lug spacing of 19mm that will certainly provide a great wrist fit, but may prove to be a bit difficult to accommodate alternative strap options due to these precise measurements. Topped by a sapphire crystal that assists with assuring water-resistance on this watch can reach up to 50 meters (167 feet).

Time is exhibited on a bead-blasted silver dial with black sub-dials and stainless-steel applied hour index markers, followed by smaller white printed minute index markers. In essence a “panda-dial” with the light on dark color-scheme. There are three sub-dials: a 30-minute counter at the 3 o’clock position; a 12-hour counter at the 6 o’clock position and a sub-seconds at the 9 o’clock position.

It’s equipped with stainless-steel alpha style hands with a contrasting red chronograph seconds hands, while Omega has chosen to use smaller white-on-black alpha hands in the sub-registers for the aforementioned: minutes, hours and running seconds sub-dials. The cursive written “Speedmaster” inscription is also in red to match the chronograph hand, adding a bit of extra color to the overall color palette.
