Accessories: Links Scratches/Cracks: None Operation: Good An homage model of the O〇ga Speedmaster. Having actually owned one, I feel that the weight and size are very similar. Advantages compared to the original: 1. Accurate because it's quartz. 2. No need for overhaul (approximately 150,000 yen every 3-5 years). 3. Good water resistance. 4. The crystal is not plastic, so scratches are less noticeable and it's less prone to fogging. 5. Above all, it's a great value. I understand why the Spima is loved by many and is popular, yet there are many being sold. In other words, I think the value of the homage lies here. I hope this is helpful.
