Antarctique

A sports watch from a dress-watch house

Czapek built its early reputation on dress watches with fine finishing and unusual dial work, so the Antarctique came as a surprise. The brand describes it as a sports watch with an integrated bracelet, which means the case and bracelet are designed as one piece. Czapek's timeline notes that the first limited edition sold out within a few weeks of its release in 2020.

The integrated bracelet is the part of the watch most likely to change over its life. Links can stretch, clasps can wear, and a replaced bracelet changes how the watch sits on the wrist. When you judge a pre-owned example, the bracelet is as important as the movement, because it is expensive to replace and easy to mistake for an original part if the seller doesn't say so.

Because the Antarctique is a sports watch, most owners wear it through heat, sweat and sometimes water. That is the reason to treat its seals as a maintenance item rather than a one-off check, and to keep a record of when the case was last opened and tested.

The SXH5 movement and what a service involves

The SXH5 is an automatic with an off-center micro-rotor, and the brand describes it as its first fully in-house caliber. It has a single barrel with a 60-hour reserve, runs at 4 Hz, and has 193 components and 28 jewels. Current versions use a rotor weight made from recycled platinum, while early examples used recycled 18-karat gold. The movement is 30 mm across and 4.2 mm thick, which leaves little room for error during reassembly.

The openworked bridges are a visual feature, and they also mean more of the movement is exposed to dust, lubricant migration and handling marks. A watchmaker should clean the movement in a way that doesn't disturb the rotor bearing, and should check the micro-rotor for free movement before reassembly. Ask the shop how it plans to handle the rotor and the bridges, and whether it will run a timing test on the finished watch.

Czapek's own maintenance guidance is a full overhaul every four to five years. For this model, that overhaul should include the new joints and seals that matter most on a sports watch, along with a water-resistance test at the end. If a quote doesn't mention the seals or the test, ask for them to be added before you approve the work.

Water resistance, seals and the bracelet

Water resistance on the Antarctique depends on the reference. The brand lists 120 metres for standard models such as the Antarctique S Polar Sky, which has a screw-down crown, and 50 metres for some gem-set versions. Those are case ratings, not movement ratings, so the number on your watch should be checked against the specifications for that reference rather than the model name.

Any work that opens the case should be followed by a pressure test, and a gasket replacement should be standard, not an optional extra. Ask whether the shop will test to the rated depth and whether it will record the result. For the bracelet, ask how the links are removed and refitted, whether the shop can refinish the bracelet without losing the crisp edges, and whether it has the right tools for an integrated design.

Czapek offers case and bracelet repolishing on request. Polishing is a cosmetic choice, and it can soften the lines of a sports watch if it is done too often, so ask to see the finish before and after. Keep the seal and bracelet work in a separate section of the estimate so you can decide on each item.

Buying a pre-owned Antarctique

Start with the paperwork. The warranty card, box and service documents should match the reference and serial number, and the case should carry the reference you were told about. Check the dial and hands against the reference, and make sure they are clean and correctly aligned. A seller who can't tell you which reference or bracelet came with the watch should lose the sale.

On the outside, look at the bracelet first. Stretched links, worn clasp parts and mismatched end links are common signs of a watch that has been worn hard or has had work done. Check the crown for a clean screw-down action and a secure seal. Ask whether the caseback has been opened, and if so, by whom. Marks around the caseback edge can suggest an opening by someone without the right tools.

Finally, ask for the movement to be checked by an independent before you pay, and for a water-resistance test if the watch is rated for it. A written report that covers the movement, case and bracelet separately is the minimum for a purchase at this level.

Choosing who services your Antarctique

For a watch still under the three-year warranty, the brand's service route is the lowest-risk option, and the watch goes back with a clear record. Out of warranty, look for a shop that works regularly on micro-rotor automatics and on sports cases with integrated bracelets. A shop that only handles simple three-hand watches may not have the right fixtures or experience for the bracelet and seals.

Ask the shop to explain its process for the rotor and bridges, its gasket and seal supplier, and how it tests water resistance. Ask for a quote that separates movement, case and bracelet work, and ask for the old parts back if any are replaced. Whoever you choose, the best sign of a good specialist is a plan you can read back in your own words.

What to check on a Antarctique

• Familiarity with micro-rotor automatics and the SXH5 layout
• Bracelet work that keeps the integrated design intact
• Pressure testing to the rated depth for the specific reference, with new gaskets
• Written estimates that separate movement, case and bracelet
