  1. "Very nice design, retro style"
    "Zeer mooi ontwerp, retro stijl"
    Jan Oudshoorn · 27 de outubro de 2025

    Since August 26 this watch is in my possession. Bought because I wanted to have and nice mechanical movement next to the quartz movements of Citizen, Seiko and Sinn which run very accurately. Read many reviews and then often criticized the lack of accuracy of the Alpinist. The first few weeks I wore it daily and there was a deviation of about a minute a week. Fine. Then I started wearing it day and night. Set date and time correctly on October 1. Reference radio controlled clock. With the onset of winter time on Oct. 26, set again. The watch was then a scant minute ahead. In daily practice, this difference is hardly noticeable. So the Seiko runs very well. I am happy and satisfied with it. The service of HWG, which I have had to use in the past, is very good. All in all, highly recommended.

    • Case quite small by modern standards (39.5 mm), good wearing comfort
    • No weaknesses

    Sedert 26 augustus is dit horloge in mijn bezit. Gekocht omdat ik wel eens en mooi mechanisch uurwerk wilde hebben naast de kwarts uurwerken van Citizen, Seiko en Sinn die heel nauwkeurig lopen. Veel reviews gelezen en vaak is er dan kritiek op het gebrek aan nauwkeurigheid van de Alpinist. De eerste weken droeg ik hem dagelijks en was er een afwijking van ca. een minuut per week. Prima. Daarna ben ik hem dag en nacht gaan dragen. Op 1 oktober datum en tijd goed ingesteld. Referentie radio gestuurde klok. Met het ingaan van de wintertijd op 26 oktober opnieuw ingesteld. Het horloge liep toen een krappe minuut voor. In de dagelijkse praktijk is dit verschil nauwelijks waarneembaar. De Seiko loopt dus heel goed. Ik ben er blij en tevreden mee. De service van HWG, waar ik in het verleden wel eens gebruik van heb moeten maken, is zeer goed. Al met al een aanrader.

    • Kast voor moderne begrippen tamelijk klein (39,5 mm), goed draagcomfort
    • Geen zwakke punten
