Three Week Update of my EternaMatic KonTiki 1958. I purchased it second hand, one month old. It is Impossible to tell that it had been worn, even upon examination with a 10x Loupe. Here are my initial impressions, modified after three weeks of wear:

First Impression

The Kontiki presents the general appearance of a classic timepiece, Round 34mm bezel outside diameter, 36mm Case width, the face is a cross between the Rolex Explorer I and the DateJust.


The case is all Stainless Steel, with a mirror polish on all surfaces except the smooth angled bezel that is finely brushed. The top sides of the case are beveled on about a 45 degree angle from lug tip to lug tip creating a style similar to the old Rolex bombe’ cases. The screw back is deeply struck with an image of the Kontiki Raft on the water. There is a shallow counter bore that affords some protection for the Crown. The screw down crown has a nice deep straight knurl and is marked with the 5 ‘balls’ that are the Eterna Trademark.


The ground of the face is a striking cobalt blue with tritium Arabic numerals at the 12, 6 and 9 positions, they are framed by metallic gold silk-screened ink. Tritium Stick markers fill the other cardinal points with the exception of the date window at 3. All the tritium markers have a decidedly green cast. Immediately below the 12 is the five ball logo and the inscription Eterna-Matic. Above the 6 is written “Kontiki 1958″. All the text is silk-screened in a gold metallic ink as are the row of ‘ticks’ at 60 intervals around the perimeter of the face.


The hands are gold sword type with a generous area of tritium filling. The sweep second hand has a tritium painted arrow shaped pointer and a small ball on the back end. The overall effect of the hands and and face together provides excellent legibility in all light conditions I have encountered as of yet.


Flat sapphire with a cyclops eye over the date window. There does not appear to be any anti-reflection coating applied.


Stainless steel, 5 rows of links. The center links are rounded on top and have a brushed finish, the inner 2 rows of links are rounded on top and are polished, the 2 outer rows are flat with a brushed finish. The filler pieces echo the scheme of the bracelet’s finish. The deployment clasp is formed of stamped stainless and is fitted with a fliplock with the Eterna name and logo. It has a substantial feel without being heavy and provides excellent comfort. It does not pull the hair on my wrists, a must.


The ETA 2428-2 is a common caliber equipped with 25 jewels and the inclbloc shock system. This one seems to be smoother to the feel when winding and setting than my other 2428-2, an Oris divers model. At this writing the watch is Approximately +1.8 seconds per 24 hours referenced to my radio controlled clock. This model is not COSC certified.


The KonTiki is presented in a blue leatherette (vinyl) covered box lined with the same material in white, with a little white pillow for the watch to wrap around. The outer box is a conventional old-fashioned stayed and covered with white leather-grained paper, chipboard. Outer box, outside of the inner box, and inside the cover of the inner boxes are hot stamped in gold with the 5 ball logo and the word Eterna.


So far I am very pleased with this watch it provides all the classic style of many much more expensive watches without the added $2k penalty for an in house movement while providing a tracable pedigree and it’s own subtle variation on the theme. The accuracy is better than I expected from a non- certified watch, so either I got lucky or Eterna spends some time regulating their calibers. Fit and finish is excellent, comparing well with my Breitling Chronomat and the rest of my collection.
